SpamAssassin Plugin Problem after upgrade

Hi,

I upgraded from the latest release candidate to 1.1.0 last night. While updating an error occured with SpamAssassin plugin, upgrade stopped with errors. After the second run i-mscp was working again, but no e-mails. On the plugin page the SpamAssasin shows an "unknown error" and you cannot change anything at the plugin. I also tried to run the SpamAssassin.pm manually from /var/www/imscp/engine/Plugins/, that causes:

That is line 34:

The only way to make E-Mails work again was to restore my old Postfix main.cf.

Any Ideas? Thank's everybody for your help!

Read my post, it doesn't
I can not uninstall an reinstall it, because there are no options (just the unknown error) in settings -> plugin management I have the following error:

I'm afraid there was no Vodka at home, so I had to take Jägermeister, and it was my right hand... maybe that was the problem

Thank you for your hints, I take another try this evening.

For everybody having the same problem, here is my solution:

after running imscp-rqst-mngr on a shell I got the following output

I started to search for Templator.pm in my backup files of 1.1.0-rc4.7 and found it in /var/www/imscp/engine/PerlLib/iMSCP/
I copied it to my working directory and set the plugin_status of SpamAssassin in imscp/plugin table to "disabled". Then activating worked in the GUI and all services are working perfectly.

EDIT by Nuxwin: All this should be put in a noobs museum but not followed.

Another hint for Postscreen-plugin: After upgrading all postscreen settings in postfix main.cf were empty -> no mails. Deactivating and reactivating the plugin in the GUI changed my main.cf to a working config.
