Version 2.6.1 of @_perfmatters is live! This is a quality-of-life update to improve compatibility across the board. 👍 - Made some adjustments to our code snippets error handler initialization logic to avoid unnecessary handling if no relevant code snippets are active. - Made additional plugin UI styles adjustments in preparation for WordPress 7. 🎨 - Updated our exception_handler method with more specific error logging when our handler is dealing with an error outside of our code snippets. - Updated Disable RSS Feeds tooltip text to reflect the recent header changes in the previous update. - Fixed an error that would occur when UTF-8 stylesheets with specific multibyte characters were parsed for used CSS. 🔣 - Fixed multiple incorrect form label IDs that showed up when creating a new code snippet. - Fixed an issue with Disable Self Pingbacks functionality that was introduced after the functions.php refactor. - Fixed an issue where a JS or CSS file preloaded dynamically by handle would not serve the minified version of the file in certain cases. 🗜️ - Fixed an issue where the inline stylesheet fallback was not always converting relative URLs correctly if certain characters were present in the string. perfmatters.io/docs/changelog/

Hey Blake, Sorry about that. We put out a hotfix earlier today. Might still be cached in a few places. Ironically, this update included our new "silo" feature, but we missed a sub-library. The good news is that going forward, this will prevent similar errors from ever happening. Thanks for understanding.

@brianleejackson @_perfmatters Just ran into an issue where 2.6.0 was throwing an error on my WooCommerce site. Deleted and manually reuploaded 2.6.0.2 from website and it's working well again. Looks like WP repository is outdated.

Version 2.6.0 of @_perfmatters is live! - Updated PHP CSS Parser library to 9.3.0. This includes many improvements for our Remove Unused CSS feature (more accurate parsing/compatibility). ⚡ - *New* perfmatters_rucss_logged_in filter that allows you to force used CSS to run when logged in (still front-end only) and create separate copies of used CSS for logged-in requests. This is experimental and only for advanced users; results may vary. - Added additional logic to used CSS generation to better deal with layer elements that are declared without a content block. - Added PHP Scoper to our plugin development workflow to be able to silo specific third-party libraries to prevent conflicts with other plugins. 👨‍🔧 - Removed built-in stylesheet exclusion for Bricks' layer files. We recommend clearing used CSS after updating. - Added new CSS helper method to rewrite relative URLs in stylesheets that will be printed inline using regex only to prevent having to pass them through the parser. This improves compatibility when using the perfmatters_rucss_inline_stylesheets filter. 👍 - Made some adjustments to clean_html regex pattern to avoid potential backtracking which could end up hitting a PCRE limit in some cases. - Made plugin UI styles adjustments in preparation for WordPress 7. 🎨 - Made improvements to visual transitions during hard reloads in the plugin UI. - Updated code snippets author column to use the user's display name instead of nice name to match the single snippet layout. - Updated disable RSS feeds function to return a 410 header instead of a 301 when requesting a feed URL. - Made some changes to plugin UI nav JS to improve compatibility when wrapper elements are added in the HTML from another source. - Fixed an issue that was causing certain attribute values to conflict with the HTML parent selector matching regex. - Fixed an issue where specific WooCommerce product types were not getting the built-in product exclusion selector added to generated used CSS. - Fixed an issue where HTML snippets with a condition mismatch were causing the original content to return blank. - Fixed an issue where code snippet input preserved in the form after a failed save request was not properly unslashed. - Fixed an issue where the code snippet code type was no longer visible and the selected value was lost after a failed save request. - Fixed a possible PHP 8.2+ deprecation warning that could occur in specific server environments during PMCS initialization. - Code snippet security updates to form submission handling. 🔒 perfmatters.io/docs/changelog/

Big shout out to @_perfmatters! Their update yesterday introduced a class conflict with Defender Pro, causing a fatal error. Emailed them, and they had a fix within 45 minutes.

@wpgaurav Wow, this looks great, Gaurav! 👏 We really appreciate all the time you put into this. We'll add this to our newsletter. And we've noted your "Cons." Some of which we're already working on. 👍 Feedback like this helpful.

Version 2.5.6 of @_perfmatters is live! Updated our lazy loading class to no longer add

On February 26th, we're doing a deep dive into why we built a performance-first code snippet manager into @_perfmatters and how you can take full advantage of it on your WordPress sites! ⚡ Shout-out to @kylevandeusen for putting this together. theadminbar.com/events/code-sn…

@PineDigitalCo @leonardo_iann We always appreciate your feedback, Ryan. And yes, these things are being addressed. 👍 Stay tuned for updates.

@leonardo_iann @_perfmatters 100% It's excellent already. There are a few small nits, like CSS variable support and some false error notifications, but those are being addressed.

Updating some websites with new @_perfmatters features with snippets. It’s really useful, and this way I can avoid using an additional plugin just for that.

@leonardo_iann Glad to hear it Leonardo! 👏 And thanks for sharing.

🚨 Issue 186 of "Loop WP", my newsletter about WooCommerce & WordPress, is out now! 🚀 WP Rocket & Perfmatters boost WooCommerce by combining caching with clean, lightweight assets for quicker loads & smoother customer journeys. Read full issue below. 👇 newsletter.loopwp.com/p/issue-186-lo…

@wpgaurav Good news, we are getting this added in our next update! However, for header CSS, we highly recommend using inline or async to fix the render-blocking, as loading CSS needed in the header in the footer could create a FOUC issue. We'll get this additional location added. 👍

@_perfmatters Team, please allow adding CSS before closing body tags as well. This will prevent render blocking, especially for not so urgent css files.

Hey @_perfmatters , a bit bottom padding in code blocks please. It hides last line for larger code blocks.
