I finally managed to get the module settings to work … I had to go into the database, find the “settings” table and manually enter the company name, currency and currency symbol.
There were no special characters (other than “€”), and now saving settings is working.
I do not know if the problem is common or not (some users had this problem in view of your forum) but it might be necessary to find out where it can come from in the event that a less knowledgeable user is affected.
Thank you !
