Fatal Error

Same here..
The website is hacked from outside. It seems that someone has access to my server now and made modification to my PHP version.
Please check as soon as possible..

Hi, did I try to upload the project to another web server if I get the same error? some other option?
thank you

A few other customers reported this as well, this is the issue with today's update of Windows Defender that barks at xtempl.php file. We have submitted all required info to Microsoft but god knows how much time will it take them to fix it.
As a solution - turn off Windows Defender, rebuild project, reupload.

it worked perfect.

thank you

I have the same problem. I did a rebuild after turning off the firewall but the problem is still there ...

Who can help me ?

One more thing. I can see that Microsoft updated the Windows Defender database. If anyone is still getting this error try the following:

Ok, I solved it, I actually went into windows defender and allowed phprunner through the firewall, as well as looked in the blocked threads and quarantined or deleted and restored those files.

I have the same problem, I disabled Microsoft Windows Defender, but the annoying problem remains.

Do you have some more info on how you solved this problem? Thanks
