JString error in language/overrides/en-GB.localise.php:93 Topic is solved

[AntonisM]

Just upgraded to joomla 4 from joomla 3.10
All was seeming to go fine but, when i tried to save an article, i got the following error:0 Class 'JString' not found
It seems that something goes on with language pack, but i have no the knowledge to find out what exactly.
Maximizing errors shows thw following:

i have installed thw latest greek language pack 4.1.2.1 and i have cleared all thw overrides i was using in joomla 3.10

Any help would be aprecciated

Welcome to Joomla forum!

The "error:0 Class 'JString' not found" indicates that there is outdated code in your website.
And because it appears when you try to save an article, I suspect that you have a non-core Content Plugin (or System Plugin) that is not compatible with Joomla 4.

Could you use Forum Post Assistant to give more information about your setup/configuration?

that is the report (seems i have to disable some plugins!)

Yes, I would (after creating a back-up) disable all non-core system + content plugins, and try saving again.
When it works ok, I would enable those plugins one-by-one, each time testing whether the save works or not.

What about the PHP file in the language/overrides folder - how did that get there and is it normal in a multilingual site?

It was supposed to be there in order to translate alias form greek to latin language in a better way than joomla did then.
How can i get red of it;

Maybe the error is produced when trying to make the alias of the article.

maybe it is not the right way but i just renamed the file en-GB.localise.php and now i can save articles with no problems.

That sounds like a good workaround.

No idea if the code would work once the JString class in line 93 is replaced because Joomla 4 may have introduced other changes, too:

Code: Select all

		$str = JString::strtolower($string);

The old JString class alias has been removed. Use \Joomla\String\StringHelper instead.
