URLs are not rewritten for CDN (keyCDN)

Is your server running in php7?

Yes, hosting is running in php7. Is that a problem?

Same problem, i use cloudfront, but this problem fix in php 5.6, try change your php version. ??

Thanks for your help. This was the solution!

Ok, i hope this problem fix in php 7 too because php 7 have more benefit than php 5.6

I had the same problem, and no need to change to earlier PHP version.

Here is an official fix. Just remove the ampersand in line 512 of TotalCache plugin’s PHP file. It’s mentioned here and here

CDN redirects work perfectly fine in PHP7.
