Can't save article - buttons do not react - save works

[Martin_Web]

Hi there,

it's like a deja vu. I had this problem years ago and can't remember what the reason was. I also googled it but haven't found the solution.

Suddenly, the [SAVE] / [SAVE & CLOSE] buttons do not work anymore. [CLOSE] does work.

I tried w/o success:
• clean caches (browser, Joomla)
• Firefox, Safari, Chrome
• activate / deactivate cache plugin


See screenshot of the browser console.

my extentions

The screenshot from the editor page shows several javascript errors in the Console tab. Those errors stop the buttons from working. Locate the javascripts from the HTML source and see which plugins or templates they originate and update those extensions.

Did your host update PHP from an earlier version to PHP 7.4 recently? Could that update have broken the extensions which dish out those javascript files?

Is the template Helix Ultimate uptodate? The latest version is 2.0.5, updated on 16 September, 2021.
