HELP 404 error after modify and save, database broken??

[LillianNest]

Hello and thank you all in advance. Since a few days, I have problems with my Joomla + Virtuemart websites. The fact is that when I make any product modification from the VM administration, when saving, the product breaks. The weblinks of the product give a 404 error, even the products do not appear to select when creating a new Product type link.

A few days ago our hosting migrated to a higher version, with more features, more php, etc ... and I don't know if something could be broken during the migration ... But on all websites?

I need ideas ... I'm going crazy about it .. new SQL Server? The Joomla version?...

If we don't modify the products from VM-Joomla, nothing happens ... all good. For example, we use a software called Store Manager for Virtuemart that works from outside with Virtuemart via bridge connection. The problem occurs when we press the SAVE button .... I hope you can help me a little, if someone needs it I will give him access where he needs it.


The webs work with an old version of VM, specifically 3.0.8 and Joomla 3.9.22. I understand that VM is quite out of date but the reason is its extreme customization. We plan to upgrade, but regardless of that, does anyone know what the hell is going on?

we need far more info than this .. facts and figures

it is entirely possible if your host has moved to e.g. php7.4 then your old versions are incompatible and the site is broken .. this is normal

but no real advice can be given as you don't incl. any relevant information
