    Hello,
    In the debug.log file I have theis warning hundreds of times every day:
    PHP Warning: preg_match(): Unknown modifier 'f' in /httpdocs/wp-content/plugins/wp-asset-clean-up/classes/OptimiseAssets/MinifyJs.php on line 116
    I know it is just a waring, but would be nice to know if everything works fine.
    Could you please have a look?
    Thank you.
    Best regards,
    Endre

    @ucsendre that’s because you have a RegEx there that is incorrectly set OR the string you’ve added is having characters that interfere with preg_match(). In fact, I was under the impression that these kinds of errors are ignored. It’s harmless anyway, it’s just filling the debug.log, that’s all.

    Can you go to the plugin’s “Settings” and then to “Optimize CSS” -> ”
    CSS Files Minification” and then let me know the values from “Do not minify the CSS files matching the patterns below (one per line):”.

    I’m considering masking this kind of error in the next version of the plugin.

    @gabelivan This is the “Do not minify the CSS files matching the patterns below (one per line):” content:
    (.*?)\.min.css
    In the php warning it says “MinifyJs.php”, so I include the contents of “Do not minify the JavaScript files matching the patterns below (one per line):” here:
    #flying-images (I have set optimisation for “All SCRIPT tags * both options”)
    I have a bad feeling about the # character. Maybe it needs to be escaped or the line is completely wrong.

    @ucsendre Asset CleanUp already appends the hash delimiter, thus the ending RegEx that is checked would be: ##flying-images#. Just remove the hash and leave flying-images and it should work. Let me know how it goes!

    @gabelivan I have removed the hash and it works fine now. Warnings are gone ??
    Thank you!

    @ucsendre I’m glad things worked out in the end. If you’re happy with the plugin overall, it would be great if you can spare a minute to leave a quick review about it here: https://www.ads-software.com/support/plugin/wp-asset-clean-up/reviews/#new-post
