I have to make changes to an image on an old Joomla site (V 3.7.4). Logging into the backend causes a server error 500.

I've updated the image (which is located in templates/shaper_helix_ii/images), however the old version of the image is still showing on the site.

I've deleted all files in all subfolders of cache/.

Is there somewhere in the file system where Joomla caches images?

I've cleared the page cache, but apparently there is a module cache, however I haven't been able to find it in the file system.

Any pointers as to where images are cached would be much appreciated.

PS: I've been using an incognito tab in Chrome, so the page definitely isn't cached locally.

  • I managed to turn off the cache with the following line in configuration.php... public $caching = '0'; /* was '1' */ ... this isn't exactly what I was after (ideally the site would stay cached) but it has achieved the purpose of making the new version of the image visible.

Cache clearing instructions can be found in the Joomla! docs here:


Here are some additional resources:

All of the above links provide tutorials with screenshots and explanations so they should put you on the right path.

There's even an extension from Regular Labs:


  • Thanks for all those resources @mickmackusa, however I've already looked at many of them. I need to be able to clear the cache without logging into Joomla (since logging in causes an error). So just using the file manager.

Helix_v2 doesn't have extra caching functionality. You just clean your Joomla default cache from the site Administrator area & check caching settings from the global configuration system tab.

  • Hi @Toufic, thanks for that. However, as stated in my question, I need to be able to clear the cache without going into the Joomla backend. It's an old site, and the backend keeps crashing when I try to log in.

It's not the Helix issue. This issue occurred for the Joomla. You should make the update the Joomla core files again. Thanks
