At https://grdins.com/new-site/ we use J51 icons in a lot of places, with a lot of data. The modules are still there but all the data is gone, all the icon data is missing.
It will be hours of work to put that all back.
I removed the html folder in the J4 version and reinstalled the template as per a forum post.
I cleared the site cache, browser cache and did a database fix on the backend also.
I opened the modules and saved and closed, also the theme.
I changed the php version and changed it back.
Can you help?
Thanks much.
