Slow Back Office - Corrupted Xml Files

[CarlosW]

I am using presta 1.6.1.4 latest version and I experience a very slow back office, but the Front Office is OK.

 

After investigating on the forum about the problem, I found out that the reason for my slow back office are 3 corrupt files:

 

default_country_modules_list.xml

modules_native_addons.xml

must_have_modules_list.xml

 

which are located in the folder .../config/xml/ and have a size of 0 bytes.
I tried to copy them from another prestashop installation and the problem was temporary fixed, I was able to work for the rest of the day without any problem. Unfortunately the next day I tried to enter the BO and the problem was there again. I checked the files above and the size was back to 0 bytes.

 

I would appreciate it if someone with a better technical understanding can provide me with some assistance to fix the problem.

Since I was not working on the BO and the eshop is not online, what has corrupted my files to 0 bytes?

I am searching for the last 3 Days in the forum, but I was only able to pinpoint the problem without a solution.

 

Thank you in advance.

See the /classes/module/Module::isModuleTrusted method. This method tries to download a new version of those files from prestashop.com every day.

 

Try to change 86400 (number of seconds in a day) in this method to a larger value.
