Hi, I am having a dolibarr installation on a server (php+MariaDb I think) and I have upgraded from 9 to 10.0.3 without issues. I have followed the procedure and everything went fine until the end. I then put back the install.lock file, and I went to log into dolibarr. I can reach the login page, but as soon as I insert the username and password, and I log in, I get a very simple message: “… is currently unable to handle your request. HTTP ERROR 500” I have checked all the permissions of the files, and they are ok. I have then tried to downgrade to 10.0.2 and things went exactly the same way. I have then re-updated to 10.0.3. Basically, I can upgrade/downgrade without issues, that section works fine. I can reach the login page, that section is fine, but I cannot go any further. Can anybody give me some tips on how to troubleshoot, as I have no idea of what is causing the issue? Anything like a log file, or maybe even some more direct tips, are appreciated. Apart from following the procedure and uploading via FTP all the new versions files, I have not touched anything else. If anyone think it could be any additional third party software that might conflict with the new update, is there a way to disable those programs without having to intervene too drastically onto dolibarr? It’s not a production platform, so I could reinstall it from scratch, but in the past months I have spent time configuring it and customizing it with some extra free dolibarr software, having to re-start all over would honestly put me off. Thanks in advance ---

Hi, I understand now, you have DolibarrDebugBar module. It should be removed, because DolibarrDebugBar is now in the CORE. Please delete /home/sites/fx2.it/public\_html/crm/htdocs/custom/debugbar ---
