easymod 0.3.0 in phpbb 2.0.21: installation problems

[felix968]

Hallo,
I've installed easymod 0.3.0: no problem report at the end of installation.
The problem is in my CP: when I click on one of mod center choose, I have this error:
"Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, postmaster@mysite and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log."

I've phpbb 2.0.21 in mkportal 1.1.1.

What can I do?
Thanks in advantage

Who is your host? Check your file permissions. Does your host require file permissions other than 644? If so, you will need to install a modified version of EM to work on your site. The answer to the questions above will tell me whether you need it or nor...

First off: switch to phpBB 2.0.22 as soon as you can.
Then.. I'm not quite sure you can have support here, due to the fact you're running phpBB on a such CMS.

If so, you will need to install a modified version of EM to work on your site.

There is only one Official Version available of EM, actually the 0.3.0.

At the present time I feel this Topic have to be Locked. Will be opened again if I'm wrong.
Thanks for understanding.
