4 Errors found message in the back office of Prestashop 1.6.1.11

Hi there,

The warning window suddenly popped up in the back office of the Prestashop 1.6.1.11 for no obvious reason.
It says:

 

4 errors

1. Error found : StartTag: invalid element name in country_module_list.xml file.
2. Error found : Extra content at the end of the document in country_module_list.xml file.
3. Error found : StartTag: invalid element name in must_have_module_list.xml file.
4. Error found : Extra content at the end of the document in must_have_module_list.xml file.

I didn't do anything the PS prior to this message to appear, except for making some adjustment to the Invoice templates files.
Everything else seems to be working OK.
 

Does anyone know what's the problem and how to fix it?

 

Thank you

Alex

clear shop cache and prestashop will download these .xml files again,

in effect - if problem is in these files - you will not see these errors again.

Thank you for the answer.

I tried to clear the cache in the Advanced Parameter > Performance window prior to posting the message to the blog.
Unfortunately, It didn't work.
However, doing the same with the "Force compilation" option selected solved the problem.

 

Thank you to everyone.
