Hi Vekia,
For 2 years I had no problem with this error. But since a few days ago, the error reappeared. For some computers of our employees the error don't happens, including my computer. Very strange, indeed.
Again, the hosting company says that is it a browser java problem, lack of RAM memory, etc.
The hosting company had a network crash and my site was not working for two days because of that.
Their mySql server crached and they had to move all to another mySql server.
I attached a browser log console image.
Please take a look. Also, I have to mention that popup message appear only for the 4 tabs marked with red color which come with the bought theme and payed modules.
If I leave only the default product tabs activated, everything it's ok. I deactivated the 4 modules and everything it's ok, but I need them to be functional.
A have to mention that I did not update anything, neither the modules involved nor the theme, prestashop, etc.
