My Custom CSS PHP & ADS


Transfered to new dev:

Maked by Esther Tyler:

With this plugin you can put custom css code without edit your theme and/or your plugins (really useful in case of any theme/plugin update).

It contain also Ace ( Cloud9 Editor) Code Editor for write a good css code.

You can see in action (source code) here: VegAmami 🙂

PS: support file backup and – very important – static css file (fantastic for performance) 😉

Updating to v3.3 breaks the complete site, including having no access to the admin board. Had to restore from a backup and replace the plugin.

I used this Plugin in +50 sites and the editor worked fine for years. Last Auto-Update to Version 3.3 crashed all my WP-Backends with several php-errors. No feedback from new developer. I deleted all my-custom-css-plugins and replaced them with another still supported css-editor-plugin.

I have used this plugin for years on many sites. But I am not happy any more. The last update (3.3) is bugged. This plugin doesn’t seem to be maintained any more seriously. I will look now for an alternative. 🙁

I had to disable the plugin. After that I was able to log in again. Now I have another editor installed. It must be related to the last update. What exactly about the error only knows the developer…

Used this for ages with no issues.. but a client site became inaccessible when we applied the latest update today so the server techs had a look and this was the issue: [fcgid:warn] [pid 27640:tid xxxxxxxxxxxx] [client xxxxxxxxxxxxxx] mod_fcgid: stderr: PHP Parse error: syntax error, unexpected ‘[‘ in /var/www/vhosts/DOMAIN/httpdocs/wp-content/plugins/my-custom-css/my-custom-css.php on line 69 Had to disable the plungin to get back in the site but now can’t access the custom CSS cide we put in this plugin for the site. Is there any way to access the custom css site settings made via this plugin, before we have to do a full site restore to the previous backup.?

  • my_style.css no more deleted if blank (but still no show in output)…
  • Now script generate blank index.html page for prevent directory listing
  • File now in “wp-content/uploads/” directory (i hope this can fix some issue with some server – sorry, i prefer to don’t touch/old user file via script – so, move yourself if u glad)!
  • Top button improved with code of another my plugin: smooth-page-scroll-to-top (some little code only for this page – a good jquery effect)!
  • Now only one (big) Saved button on top-right (fixed)!
  • Now backup button is on bottom/left.

Thanks to this I can see custom css code in admin panel via database and put in source via file with ‘@import url(“my_style.css[+ ‘?filemtime’ to fix browser cache]”)’.
