I need a fixed Price for this - and an agreement that i don't pay if you fail to fix the issue.

 

Kind regards

Hi,

 

I guess I'm the right person to answer the questions above. As I really appreciate the attitude to help the community, I felt also reponsible and after having mpeg69's consent, I just wanted to answer. Please let's keep this point mentioning not only in this topic.

 

The issue wasn't caused by a general bug in the spesific configuration. mpeg69 had two separate modules coming together with his theme and those modules were the main source of the problem.

 

After having fixed those, the page load speed decreaed until 5 secs, and with the intervention of my module caching the modules selectively by module/hook, the speed saw two or three seconds per page, as it is actually now.

 

I hope this helps.
