I made a fresh installation with iRedMail 1.3.1 on CentOS 7. The installation went fine. After the reboot I wanted to log into iredadmin and I always get the error message "Internal Server Error".

I find no error messages in the logs? Is there a specific log for iredadmin? I couldn't find any information about a log file in the iRedMail.tips file either.

OK I found out that the logs are in the normal messages file.

Here is the real problem:

uwsgi: Traceback (most recent call last):
uwsgi:  File "/opt/www/iRedAdmin-1.0/iredadmin.py", line 9, in <module>
uwsgi: 
uwsgi: from libs import iredbase
uwsgi:  File "/opt/www/iRedAdmin-1.0/libs/iredbase.py", line 7, in <module>
uwsgi: 
uwsgi: import web
uwsgi: ImportError
uwsgi: :
uwsgi: No module named web
uwsgi: 

It looks like something was not installed during installation.

After some more investigation:

[root@server iRedMail-1.3.1]# pip3 install web.py

SyntaxError: invalid syntax

So the problem is that web.py was installed with python3. Because with python3 the script can be started. But then we have syntax error. So it looks like right now no installation is possible which gives us a stable set-up.

iRedAdmin(-Pro) relies on Python 2, not 3.
Please run commands below to fix it:

pip2 install web.py==0.51
service iredadmin restart

Will double check and fix it, then repack iRedMail-1.3.1.

We're working on moving iRedAdmin(-Pro) to Python 3, SQL edition is done, but LDAP edition requires huge changes, it will delay for some more time.

Some more detail if you're interested in: web.py team released a new version 0.60 yesterday, but it's not marked as Python 3 (>=3.5) only. But iRedMail installer installs web.py with >=0.51 flag, this way it installs 0.60 instead of 0.51 and failed.

Update: re-packaged iRedMail-1.3.1 with pip issue fixed.

I have the same issue ("internal server error" after fresh install)
Absolute fresh Debian 10, fresh installation, I did everything absolutely according to the book.

pip2 install web.py==0.51 did not fix it.

But by first installing python-setuptools (apt-get install python-setuptools)
and afterwards installing web.py (pip install web.py==0.51) it worked!

During installation it already showed the problem:

Collecting web.py==0.51

Dear @UweKrause

Please install package python-setuptools first, then install web.py with pip:

apt install python-setuptools
pip2 install web.py==0.51

You are an absolute legend! Thank you!

I had to do: pip3 install web.py==0.61

Once I did that, my upgrade to 1.7 worked.

Thanks again!
