Issue with currency symbols

hello,

I have tried to change the symbol in the Square Feet field from qm to m2. And back again to qm.

Since then, no symbols are displayed to me. And no price currency $ € ....

What can I do? I need the currencies back.

Kind regards

Hello,

How did you do it? Via database?

Try to refresh the system cache: Common > Refresh

or send me your ftp details to my PM and I'll look into it

I had Refresh System Cache and etc... under Common > Refresh.

I'll send you PM with ftp details.

The cause was file caching, with insufficient write permissions.
While searching for the error, Rudi disabled the cache, and the problem with the missing icons was solved.
In the second step, I adjusted the read/write permissions to the /tmp folder, and enabled the cache at the file level.

I have nowhere found an overview of which folders and files should have which rights.

Many thanks to Rudi.
