I have installed it several times and I can not install anything from the App Store ... Always the message of Internal server error ...

Let's see if anyone can help us ...

Thanks in advance...

Hello,

Server errors after installing new thing (i.e. module) comes (at leas as per my experience) in problems with editing files done during installation. if such a thing happen (luckili it is rare case) I am checking logs, and looking for modified files comparing these to base install. in case of linux systems:

1) checking files mentioned in odoo log file:

for i in `tail -100 odoo-server.log | grep "File \"/usr" | awk -F\" '{print($2)}'`; do ls -la $i; done

above command gives me last files mentioned in odoo log; I am looking for file(s) changed lately, just after last change/installation

2) if there will be any file just modified found, I am just making copy of it, and replacing with same file from working (base) installation

sound stupid but.. so far always when having server error was able to quickly find guilty file. I am not considering here what was root case (how come file was broken/changed in wrong way), but as a solution it could - I hope - help.

regards
