Hi Kingsley,

please try to investigate issues with the investigation from access- and error - logs and its depending configuration files.
If you need help with that, please post relevant entries and config - files and be sure to always include your operating system and the Plesk version you use ( incl. MU ), as well as the information from "php -v".

Parallels Plesk Panel for Linux services logs and configuration files ( KB - article: 111 283 )​

P.S.: It's makes it a lot easier for people willing to help, if you use CODE - brackets for "copy and paste" - informations from logs and configuration files, here in the forums. Please see the 4th - BB-Code - button from the right in the navigation - bar of each Editor - Box ( "Insert..." ).

I use

Plesk 12.0.18
Centos6.6(final)
1GB RAM

2 wordpress
1 html site

For the most part having installed (but deactivated plugins) won't impact performance as WordPress doesn't actually include plugins if they are not activated.

Assuming that PHP is running via Fast-CGI, have you considered returning a 403 for any attempts on the login page to see if activity subsides? This might be indicative of basic WordPress brute forcing which causes your entire WordPress install (including activated plugins) to load with each attempt and can create some pretty significant loads for a 1 GB VPS.
