Slow Dashboard loading time

[psychogav]

All of a Sudden, My dashboard loading time has become very long indeed, adding products is a nightmare, as is just moving around in my back end, what could be causing this?

Yes, am experiencing the same exact thing!

v1.6.0.6

 

Actually it is the entire backend that is slow, not only the dashboard.

Frontend is working and the speed is normal though.

After having disabled the must_have_modules_list.xml and default_country_modules_list.xml in  config/xml/  i did notice a huge speed difference.

The modules page now loads as normal, but all the other pages in the backend are taking 40s instead of 0.7s

 

Really would like to know how to fix this

I have a feeling it does have to do with certain modules or scripts loaded from prestashop.

Based on the previous finding, that when removing the must-have and default country modules, the page does render fast as it should.

 

So i'm curious, what modules are loaded in each page in the backend that was also present in the must-have and default-country modules list?

Could it be (somehow) related to paypal since paying with it also results in an error ?

 

paypal results in  the following
