Internal Server Error when Minifying CSS (yes I checked FAQ)

(@fenosc)

Hi,

I read a bunch of topics here and also went to the FAQ page to see if there was something about what I fighting, no success.

Environment Context
I have the latest Autoptimize and also W3 Total Cache. In W3 Total Cache I have only Page/Browser Cache enabled (therefore Minifying is disabled). In Autoptimize I have only JSS Minifying enabled (with all sub-items disabled) and I exclude “seal.js, js/jquery/jquery.js”.

The issue
When I enable CSS Minifying and hard refresh my page it loads until I get an error. PageSpeed Insights and GTMetrix get an error as well. I did troubleshoot to see which one exactly was causing the error (meaning that I deactivated W3 Total Cache, testes Autoptimize only and isolated the issue around CSS Minifying. Currently I have everything else ON and CSS Minifying OFF and the site is working fine)

Attempt to resolve
Out of the many things I searched for, I tried enabling the legacy minifying in wp-config.php, per FAQ suggestion, but that didn’t work. Tried re-enabling it again and again with no success.

Below my system configuration

first of all; thanks for really reading the FAQ and applying that info! seriously, you don’t know how many times I have to tell people to do just that … 😉

now I had a look at your site and it seems you have Autoptimize active now and all works OK? if you still have problems you’ll have to try excluding CSS-files one by one until you find the one that breaks the optimizer.

(not related to AO, but that designer_css.php CSS file is linked as stylesheet, but it contains CSS wrapped in HTML <style type="text/css"></style> so that might result in the CSS not being applied).

Hi, thanks for the quick answer!
Now, I am not a pro (and I know you read this a lot), so I’d like to know if you could be a bit more specific on how I can approach this.

1) “Excluding CSS-files one by one” – How would you approach that without breaking the website? I do know how to get into the FTP, find those files and delete them but I don’t even know what those CSS files are doing. I mean, they were created by so many plugins that I can’t tell what they specifically do. Would it be like renaming them and turning Autoptimize on and check whether it breaks or not?

2) Funny you mentioned that “designer_css.php” file which is a pain in the ***. It is pointed as an “above the fold” error and it was created by a plugin. Do you have any idea on how to fix it? I have no idea what is the problematic relation you have with “linked as stylesheet” and “contains CSS wrapped in HTML <style type=”text/css”></style>”.

Thanks!

re (1); don’t remove any files from your server @fenosc ! what you want to do is go to your site with AO disabled (just add ?ao_noptimize=1 to the URL to do that) and then view source that page. in the resulting HTML you’ll see the CSS-files referenced, which you can then try to exclude (cfr. FAQ for info how to exclude).

re (2); you’ll have to check with the plugin developer. the problem I tried to point out is that a CSS-file should never contain those HTML tags, it should just be CSS.
