my error log has been filling up for some time with the following error message:
preg_match(): Unknown modifier ‘p’ in /www/xxx/html/wp-content/plugins/cache-enabler/inc/cache_enabler_engine.class.php on line 335′
There was a topic about this here, but it was not helpful:

My settings for Cache Exclusions > Page Paths setting
/wp-content/uploads/woo-feed/
The error has been occurring for months and started sometime after updating to All in One SEO 4.1.0.2. Updating to other versions of the software has not helped.
If you search for the error in Google, you see many other people are having this issue too.

I have the WP Safe Mode plug-in, which I activated, but the warnings stayed. I tried switching themes from my Ice Cold child theme to twenty-twentyone, but the warnings stayed.
I am relatively new to all of this; I know that this is a “warning”, but when I go to view a post, this is copied on that page (at least as a logged-in administrator); the site is under development, not yet live (a transition from Joomla in progress), so IDK how live posts would display.
I just checked the site health status screen; imagick has been shown as missing before, so that does not worry me; I see that the REST API did not process context correctly, IDK what that means, nor do I remember seeing that before. Also, I see that the “authorization header”, which apparently comes from 3rd-party applications (of which I don’t remember approving any), is missing.
WP version 5.7.2; PHP 7.4.18; SQL server up to date; 13 other tests passed.
Any help is welcome.
An error message saying

appears on my homepage and a few random posts.
Also, on WP Cleantalk dashboard there is another error message, please see below:

Kindly advise how to solve this. Please as simple as possible as I am not a programmer, so I can understand the steps to take to fix this (in case I have to do something at all?)
Thank you

Thought you should know.

I posted already in another thread, but because the other thread is general resolved, I think it is not pushed anymore and nobody will find it:

I have the same error after upgrading my install of W3 Total Cache to version 0.14.1 on:
WordPress version 5.4.1
Server architecture Linux 4.19.113-combell x86_64
PHP version 7.4.6 (Supports 64bit values)
I am facing the following error:
PHP Warning: preg_match(): Compilation failed: quantifier does not follow a repeatable item at offset 0 in /data/sites/web/URL/www/wp-content/plugins/w3-total-cache/PgCache_ContentGrabber.php on line 952′
PHP Warning: preg_match(): Compilation failed: quantifier does not follow a repeatable item at offset 0 in /data/sites/web/URL/www/wp-content/plugins/w3-total-cache/PgCache_ContentGrabber.php on line 952′
I have the following “Never cache the following pages” settings:
wp-.*\.php
index\.php
Question is: how to solve this?
I see also periodically my site is going down for a minute of so.
Thanks in advance,

I can’t get any folders to be excluded.
No matter what input I try, I get:
Warning: preg_match(): Unknown modifier ‘/’ in /site_root/public_html/wp-content/plugins/organize-media-library/lib/class-organizemedialibrary.php on line 200
I’ve tried the following for a folder called “avatar-cache” located in /wp-content/uploads/avatar-cache:
/avatar-cache
\/avatar-cache
[/avatar-cache]
[\/avatar-cache]
~/avatar-cache~
~\/avatar-cache~
The modifier that is reported as unknown changes based on my input, but the error and line number remain consistent.
I do notice after hitting “Make Folder & Save Changes”, the “\” character is always stripped from my last input.
When I submit:
\/avatar-cache
The admin page reloads with the preg_match warning, and the exclude value shown is always (“\” stripped):
/avatar-cache
That most certainly seems to be the issue.
I’ll try disabling my plugins and the usual routine, but I can’t think of any right now that affect admin form inputs….let alone stripping values from admin form inputs. I’ll check back and perhaps you have some ideas as well.

It would actually be great if this auto-featured-image were a part of WordPress core code, so that whenever you upload one image you could have that just be the featured image by default.

At the last pages on that thread, also other people still write about problems and I see no solutions on the thread.
I have updated WordPress and W3 Total Cache, both to newest version, and face an error now:
Compilation failed: quantifier does not follow a repeatable item at offset 0 in */w3-total-cache/PgCache_ContentGrabber.php on line 920
In complete:
Warning: preg_match(): Compilation failed: quantifier does not follow a repeatable item at offset 0 in /www/htdocs/USER/SITE.com/wp-content/plugins/w3-total-cache/PgCache_ContentGrabber.php on line 920
Warning: preg_match(): Compilation failed: quantifier does not follow a repeatable item at offset 0 in /www/htdocs/USER/SITE.com/wp-content/plugins/w3-total-cache/PgCache_ContentGrabber.php on line 920What is the solution for this?
Also the plugin seems to be deactivated and even when I activate it and WP says it is activating is, after refresh my plugins overview it shows like it is deactivated. Any ideas about that related to that “PgCache_ContentGrabber.php on line 920” error?
