Upgrade MAMP 7.1 to 7.2 – Internal Server Error

[kaz]

I use MAM Pro on macOS. At the last launch I was notified of an upgrade from 7.1x to 7.2, which I confirmed.

After the upgrade, when opening sites, also localhost, the following error message appears in the browser:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at you@example.com to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.
Apache/2.4.62 (Unix) mod_wsgi/5.0.1 Python/3.12 mod_fastcgi/mod_fastcgi-SNAP-0910052141 OpenSSL/1.1.1w Server at my-site.local Port 8891

I have contacted the support and got the following answer:

"You may have to completely reinstall the app.

I have backed up the databases and hosts and reinstalled MAMP. I restored the database and created the hosts manually. So far, so good.

Unfortunately, the error message remains almost identical for the hosts, only the port has been changed from 8891 to 8890:

SSL certificates are included with all rights in the keychain administration. Perhaps Processwire cache? I have no idea where else to look.
I have the original hosts outside of MAMP in the folder /sites/..., and also SQL backups from phpMyAdmin, – is there a possibility to restore single projects from it? PW reinstallation, importing of a database, ... is there a possibility to rebuild projects with these data?

MAMP Pro should allow you to enable screen output of errors for PHP when you're in expert view. That should give you a better idea of what's going wrong.

Is the issue still happening for localhost as well? Also, have you tried to create an empty MAMP project with just an index.html (or even a simple index.php) to rule out a MAMP issue?

I did the update to 7.2 and didn’t have any issue.

@BitPoet In version 6 I had the view mode icons for switching, in 7 they are missing. It is also missing in the ver. 7 online help. mmhhh?

@monollonom localhost works again, the installation was correct. // The new site was set up successfully.

Is the issue with MAMP itself or your website? Can you dump out php errors?

I’m using latest MAMP + ProcessWire without issue.
