Dear I have Problem with my Prestashop. I am using Prestashop 1.5.6.0 with a purchased Theme / Template. Before some Months I could always get on my Online Store Login or without any problem with the Hosting Connection. But from 6 April 2015 has started to Block my Online Shop Site from the Firewall of Hosting place which is my Prestashop Installed. I was contacting my Hosting place there told me that the firewall has block my Online Shop. The Hosting place has connected my Online Shop and after some days again the same Problem happen, this is now 3 times happen. Hosting Place told me (It could be that your software has vulnerabilities and therefore blocked by the firewall). Just now I was trying to open cms folder for Uploading Picture or putting the picture and has started this Problem (Please see the Step Picture). After Step 4 and after this error (SyntaxError: Unexpected Token <) begins to block my site from Hosting Firewall. After this I am not more able to connect my Online Shop. Can anyone help to make this proper? Sorry for my weak English. Thank you Best Regards
