Ok because you're not using php-fpm. After rerunning apache, is your problem solved?
BTW: Please also check the database and upgrade imscp to the 1.3.x branch. You're using an old version..

BTW: Please also check the database and upgrade imscp to the 1.3.x branch. You're using an old version..

Is it recommended to use already 1.3.X? It still says "partial working"

Ah @Nuxwin branch informations in forum are wrong. Current 1.3.x is stable, unstable old 1.3.x was moved to 1.4.x.

Hello,

in the Logs you can see the problem: AH00287: server is within MinSpareThreads of MaxRequestWorkers, consider raising the MaxRequestWorkers setting !
Please increase the PHP-FPM Setting: MaxRequestWorkers to solve the problem.

Open the file: /etc/apache2/mods-enabled/mpm_worker.conf and modify the paramters. After them restart php-fpm with these commands:

/etc/init.d/php5-fpm restart
/etc/init.d/apache2 restart

Good settings on high load wordpress sites here are:

MinSpareThreads 64
MaxSpareThreads 256
MaxRequestWorkers 2000

regards,
MENKI
