php illegal string offset warning in logs

OK, I’ll look into those @willjames, more soon(ish) ??

and thanks for testing the Beta!

OK, think I identified and the problem and found the solution, can you re-download the beta and upload the zipfile to update your installation @willjames and then remove all rules (you’ll probably see a great deal of those with “critical css file” set to “undefined”, so those are broken) ?

Thanks – remind me where I download the beta file from again? Only 2 of the AUTO CCSS jobs had ‘undefined’

sure; https://github.com/futtta/autoptimize/archive/refs/heads/beta.zip

re. rules; you can remove just those 2, others can stay ??

Thanks – I have done this a new error on the logs:

from this page:
https://www.truckpages.co.uk/vans-for-sale/

AH01071: Got error 'PHP message: PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 28672 bytes) in /var/www/vhosts/truckpages.co.uk/httpdocs/wp-content/plugins/unusedcss/includes/modules/unused-css/UnusedCSS_DB.php on line 939PHP message: PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 81920 bytes) in /var/www/vhosts/truckpages.co.uk/httpdocs/wp-content/plugins/duplicate-post/vendor/composer/ClassLoader.php on line 571PHP message: PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 81920 bytes) in /var/www/vhosts/truckpages.co.uk/httpdocs/wp-content/plugins/wp-asset-clean-up-pro/classes/OptimiseAssets/OptimizeCss.php on line 533'

Afraid memory exhaust issues are rarely due to one plugin willjames; the errors mention unused-CSS (rapidload), “duplicate post” and “wp asset cleanup”, but all in all memory issues are due to many a straw breaking the camels back. try taking some straws off or make the camels back stronger by increasing PHP memory size?

I had ticked some of these boxes in Rapidload and it caused the problem – unticked them all and OK now.

Minify -- Minify and Remove CSS comments via the API (THIS WAS ALREADY TICKED AND OK)

 CSS Variables -- Remove unused CSS variables

 CSS Animation keyframes -- Remove unused keyframe animations

 CSS @font-face rules -- Remove unused @font-face rules

 Inline CSS -- Optimize Inline CSS

 Cache Busting -- Enable RapidLoad crawler to view pages with a random query string

happy it works that way, but do keep in mind memory issues might still be lurking around the corner even of you removed some straws of the camels back ??

have you tried some of the new features in the beta already?

Hi
I have tried to work through the new features of 2.0 but after unchecking the ‘aggregate js files’ and ‘aggregate css files’ i found that some of the CSS was not being deferred at all leading to large issues in page speed. I have CCSS set up and it seems to be working but the following files still show as render blocking:
/wp-includes/css/dist/block-library/style.min.css?ver=5.9.2
autoptimize_single_9d9b573802f7cbb5a8967eb9af830f06.css?ver=5.9.2
autoptimize_single_7ffae3dbc7bc585c36649749de14d8b8.css?ver=1.0.0.1.1581000692
autoptimize_single_5c172d407053946161c2ad8117830e68.css?ver=668
/wp-content/themes/motors/style.css?ver=1.0.0.1.1581000692

I have taken out any exceptions that I had for CSS and JS when aggregated. Can’t understand why just these files are being called out as render blocking?

Info: I have also selected the ‘remove global styles’ feature.

Additionally, I used to add the name of the page I have added a manual ccss file to – so that I know that any changes have been updated and the correct CCSS is being called (for example .homepagev22{}) then I knew that if this was at the end that was the version of the homepage manual ccss. The system now seems to strip this off the end of the files?

thanks for the feedback!

-> re. render blocking CSS; I just looked at the Pagespeed result for the homepage and no CSS is being called out as render-blocking. what page did you get that message on?
-> re. the name of the page; AO will now automatically minify inline JS/ CSS and that will likely also impact “empty” CSS-selectors. add some dummy CSS in there (e.g. .homepagev22{a:b;}) or enable “keep HTML comments” or use the code snippet below to disable inline CSS/ JS being minified;

add_filter( 'autoptimize_html_minify_inline_js_css', '__return_false' );

I have just run on homepage and the same files are being called out – I have been trying different options but it is now back to where it ‘should’ be except it is not deferring these css files.

Not entirely sure what is happening here (esp. as there are no differences in how CSS is optimized/ deferred between 2.9.x and 3.0 beta), but I have seen those files being flagged as render-blocking and then … not;

I checked the HTML source and the files mentioned are indeed deferred using the Filementgroup’s CSS deferring method so, I cannot but conclude that PageSpeed Insights is flipping a bit? ??

Is there a recommended route for the trial and error that I am carrying out here? with CCSS, Rapidload, WP Super Cache and AO I think I tie myself up in knots.

There are a lot of caches to clear each time I change a setting and they sometimes take a while to rebuild…?

It seems that an upgrade to my theme saw it introduce their own critical css system – not sure if this is conflicting and causing bloat as well in the header? Have you seen anything like it before?

However, my largest problem that I am facing at the moment is that I am getting mixed content messages as Rapidload files seem to be requesting fonts from http: rather than https:

Have you had any other examples of this happening?

Thanks

Sorry – We crossed over in messaging – I hadn’t seen your note prior to sending mine and vice versa).

I had this issue before with the fonts that the CCSS was injecting the http rather than the https: into the inline css even though there is no instruction to do so in the original css

I have turned off CCSS and turned on the Rapidload one which seems to be working better, except that the main AO css file is now being called out as render blocking (when aggregating) or if not aggregating then there are 5 css files showing as render blocking.

The Rapidload critical css seems to work better than the CCSS one however.
