If you want optimize jquery as well, you can remove it from the JS optimization exclusion-list (you might have to enable "also aggregate inline JS" as well or switch to "force JS in head"). | |

| 49 | 54 | |
| 50 | -If not "forced in head", Autoptimized JS is not render blocking as it has the "defer" flag added. It is however possible another plugin removes the "defer"-flag. Speed Booster Pack was reported doing this, but [the behavior has not been confirmed yet](https://wordpress.org/support/topic/speed-booster-pack-autoptimized-js-defer-flag/). | |

| 62 | 67 | There's no easy solution for that as "above the fold" depends on where the fold is, which in turn depends on screensize.

| 64 | 69 | = Or should you inline all CSS? = |
| 65 | 70 | |
| 66 | -The short answer: probably not. | |
| 71 | +The short answer: probably not. Although inlining all CSS will make the CSS non-render blocking, it will result in your base HTML-page getting significantly bigger thus requiring more "roundtrip times". Moreover when considering multiple pages being requested in a browsing session the inline CSS is sent over each time, whereas when not inlined it would be served from cache. Finally the inlined CSS will push the meta-tags in the HTML down to a position where Facebook or Whatsapp might not look for it any more, breaking e.g. thumbnails when sharing on these platforms. | |
| 67 | 72 | |
| 68 | -Back in the days CSS optimization was easy; put all CSS in your head, aggregating everything in one CSS-file per media-type and you were good to go. But ever since Google included mobile in PageSpeed Insights and started complaining about render blocking CSS, things got messy (see "deferring CSS" elsewhere in this FAQ). One of the solutions is inlining all your CSS, which as of Autoptimize 1.8.0 is supported. | |
| 69 | - | |
| 70 | -Inlining all CSS has one clear advantage (better PageSpeed score) and one big disadvantage; your base HTML-page gets significantly bigger and if the amount of CSS is big, Pagespeed Insights will complain of "roundtrip times". Also when looking at a test that includes multiple requests (let's say 5 pages), performance will be worse, as the CSS-payload is sent over again and again whereas normally the separate CSS-files would not need to be sent any more as they would be in cache. | |
| 71 | - | |
| 72 | -So the choice should be based on your answer to some site-specific questions; how much CSS do you have? How many pages per visit do your visitors request? If you have a lot of CSS or a high number of pages/ visit, it's probably not a good idea to inline all CSS. | |

In this case you can turn on the option "Look for styles on just head?" and see if that solves the problem. You can also force CSS not to be aggregated by wrapping it in noptimize-tags in your theme or widget or by adding filename (for external stylesheets) or string (for inline styles) to the exclude-list. | |
| 143 | -* In case some functionality on your site stops working (a carroussel, a menu, the search input, ...) you're likely hitting JavaScript optimization trouble. Change the "Aggregate inline JS" and/ or "Force JavaScript in head?" settings and try again. Excluding 'js/jquery/jquery.js' from optimization (see below) and optionally activating "[Add try/catch wrapping](http://blog.futtta.be/2014/08/18/when-should-you-trycatch-javascript/)") can also help. Alternatively -for the technically savvy- you can exclude specific scripts from being treated (moved and/ or aggregated) by Autoptimize by adding a string that will match the offending Javascript or excluding it from within your template files or widgets by wrapping the code between noptimize-tags. Identifying the offending JavaScript and choosing the correct exclusion-string can be trial and error, but in the majority of cases JavaScript optimization issues can be solved this way. When debugging JavaScript issues, your browsers error console is the most important tool to help you understand what is going on. | |

| 226 | 225 | Google Fonts are typically loaded by a "render blocking" linked CSS-file. If you have a theme and plugins that use Google Fonts, you might end up with multiple such CSS-files. Autoptimize (since version 2.3) now let's you lessen the impact of Google Fonts by either removing them alltogether or by optimizing the way they are loaded. There are two optimization-flavors; the first one is "combine and link", which replaces all requests for Google Fonts into one request, which will still be render-blocking but will allow the fonts to be loaded immediately (meaning you won't see fonts change while the page is loading). The alternative is "combine and load async" which uses JavaScript to load the fonts in a non-render blocking manner but which might cause a "flash of unstyled text". |

| 330 | -* Improvement: refactored the page cache purging mechanism (removing duplicate code, now nicely hooking into AO's own `autoptimize_action_cachepurged` action) | |
| 331 | -* Improvement: Re-enable functionality to move non-aggregated JS if "also aggregate inline JS" is active (can be disabled with `autoptimize_filter_js_unmovable` filter) | |
| 332 | -* Improvement: script tags with `data-noptimize` attribute will be excluded from optimization | |
| 333 | -* Bugfix: Better support for renamed wp-content directories | |
| 334 | -* Bugfix: Multiple fixes for late-injected CSS/ JS (changes in those files were not always picked up, fonts or background images were not being CDN'ed, ...) | |

Code [contributed by Joern Lund](http://wordpress.org/support/topic/multisite-blog-admin-can-delete-entire-network-cache), kudo's Joern!! | |
| 400 | -* Improvement: add WordPress plugin header to autoptimize_helper.php_example to make it easier to enable it as a module | |

| 400 | +* some other minor changes/ improvements/ filters, see the [GitHub commit log](https://github.com/futtta/autoptimize/commits/beta). | |

| 423 | += 3.1.1 = | |
| 424 | +* images: when optimizing images and lazyloading is on, then by default do not set an LQIP (low quality image placeholder) any more (reason: it might *look* nice but it comes with a small-ish perf. penalty). This can be re-enabled by returning true to the `autoptimize_filter_imgopt_lazyload_dolqip` filter. | |
| 425 | +* security: further improvements to critical CSS settings page (again with the great assistance of WPScan Security). | |

| 430 | +* new Misc option: permanently allow the "do not run compatibility logic" flag to be removed (which was set for users upgrading from AO 2.9.* to AO 3.0.* as the assumption was things were working anyway). | |
| 431 | +* security: improvements to the critical CSS settings page to fix authenticated cross site scripting issues as reported by WPScan Security. | |
| 432 | +* bugfix: "defer inline JS" of very large chunks of inline JS could cause server errors (PCRE crash actually) so not deferring if string is more then 200000 characters (filter available). | |
| 433 | +* some other minor changes/ improvements/ hooks, see the [GitHub commit log](https://github.com/futtta/autoptimize/commits/beta) | |

| 443 | +* ensure critical CSS schedule is always known. | |
| 444 | +* when deferring non-aggregated JS, make the optimatization exclusions take the full script-tag into account instead of just the src URL. | |
| 581 | 445 | |
| 582 | -= 0.5 = | |
| 583 | -* Support localization | |
| 584 | -* Fix the move and don't move system (again) | |

| 452 | +* fix for regression in import of CSS-files where e.g. fontawesome CSS was broken due to being escaped again with help of @bobsled, thanks man! | |
| 595 | 453 | |

| 597 | -* Disable CSS media on @imports - caused an infinite loop | |
| 454 | += 3.0.0 = | |
| 455 | +* fundamental change for new installations: by default Autoptimize will not aggregate JS/ CSS any more (HTTP/2 is ubiquitous and there are other advantages to not aggregating esp. re. inline JS/ CSS and dependancies) | |
| 456 | +* new: no API needed any more to create manual critical CSS rules. | |
| 457 | +* new: "Remove WordPress blocks CSS" option on the "Extra" tab to remove block- and global styles (and SVG). | |

| 460 | +* improvement: defer inline now also allowed if inline JS contains nonce or post_id. | |
| 461 | +* improvement: settings export/ import on critical CSS tab now takes into account all Autoptimize settings, not just the critical CSS ones. | |
| 462 | +* technical improvement: all criticalCSS classes were refactored, removing use of global variables. | |
| 463 | +* technical improvement: automated unit tests on Travis-CI for PHP versions 7.2 to 8.1. | |
| 464 | +* fix: stop Divi from clearing Autoptimize's cache [which is pretty counter-productive](https://blog.futtta.be/2018/11/17/warning-divi-purging-autoptimizes-cache/). | |
| 465 | +* misc smaller fixes/ improvements, see the [GitHub commit log](https://github.com/futtta/autoptimize/commits/beta) | |
