I'm using the Helixultimate Template (2.0.18). Previously in a Joomla 3.1 website, which I migrated to 4.4. Everything looked fine and seemed to work. But at a second glace some pages (single content) produce "500 behavior::caption not found". Can I fix it?

Marked as the solutionHi Susanne,
I saw you renamed template, and I don't know if you updated all files inside /html folder from your current template to be sure if site is using a new code, hmm?
I suggest two steps:
- Install raw Helix Ultimate template and set it as default template for a while (5 min) , and check those subpage again where you saw Error 500.
- If (1) will not help to remove problem then in Global Configuration enable that to see more details about source of error

Hi,
Thank you for your help. As you might guess, I'm not a professional and dealing with the website is always a bit try and error...
I re-installed the raw version of Helix ultimate and the same error came up (after more than 5 min). This is the report:

I was thinking of redoing the modifications in the template from scratch - but if the raw template doesn't work either, this is no point.
By the way: I get the same situation in another version in a subdomain with Joomla 5 and a different database.
Re-Edit:
I saw in line two that the template still refers to my modified template even if it is no longer standard. In my Joomly 5 subdomain I completely deleted the modified template and reinstalled helix ultimate. This fixed the error. (http://2024.rgzv-delbrueck.de/verein.html)
But now I sadly have to redo my template.
That file must be removed, somebody made a mess.

in that folder should be only two files:
- default.php
- default_links.php
compare with raw Helix Ultimate template/quickstart
Wow great! This did the trick.
Thank you very much!
