I have made as you have advised to me it seems to work, but still have some problems.
1) the currency remains set up on US dollars.
2) when I edit a content I receive this message:
alert("MDB2 Error: no such table\nSELECT extension, plugin FROM kfm_plugin_extensions WHERE user_id=1")
3) when I modify in manage design a theme, it´s not changing it´s erasing
the last question is: if I install PS4.5 from zero with a new database, will it work?
Please test it by yourself:
