Hello,

I’ve created a staging version of my forum; the upgrade went smoothly, but when I press the rebuild tool button in the ACP, I get a 500 error:

Class IPS\rebuildtools\Application could not be loaded. Ensure it is in the correct namespace.
 

I don't know how fix the problem 🥲

You would need to contact the author of that particular 3rd party item for assistance with that

I don't even remember that was a 3rd party item! Thank you, then can I delete it?

As its a 3rd party item we didnt add and dont know its purpose, there is no way we are able to answer that

I have deleted it and now the forum works 🙂
