1 - Check your server's error log.

2 - Have you any problems with another URLs?

Read this and this also.

Thanks a lot.

But now I got the following error.

"Elgg cannot connect to itself to test rewrite rules properly. Check that curl is working and there are no IP restrictions preventing localhost connections."

My apache configuration looks as followed.

 <VirtualHost _default_:443>
                ServerAdmin webmaster@localhost
                ServerName pessek-elggfinal331.com

Hi everyone,

Could someone help me on this issue ?

Regards,

I would run the clear the cache and upgrade once using cli. Trying running the below command using your terminal and then check if the upgrade through the admin panel is working or not.

# Clear caches
vendor/bin/elgg-cli cache:clear

# System upgrade
vendor/bin/elgg-cli upgrade

# Upgrade and execute all async upgrades
vendor/bin/elgg-cli upgrade async

Thanks.

I did that. But I still got the same error when I try to upgrade through the admin panel.

vendor/bin/elgg-cli cache:clear

The site's caches have been cleared 

vendor/bin/elgg-cli upgrade

System has been upgraded 
Plugins have been upgraded

 vendor/bin/elgg-cli upgrade async
 System has been upgraded

Regards.
