What's the debug-logging tool finding?

Hi

It has done nothing it did not log anything, there has not been any log page created in the temp directory

only log that was received is via email...

Do you know what is maybe causing this?

A blank page appears when a fatal PHP error occurs. That can happen when you edit files (typically language/template files, but not isolated to those) and introduce PHP syntax errors. It can also happen when your FTP upload process fails to fully/completely upload all files when you're uploading them to the server. Sometimes that can result in partial files, or files with no content, or even missing files. It can also happen when installing poorly-written addons or installing them to the wrong folders or haphazzardly.

While the debug-logging-tool mentioned here: https://www.zen-cart.com/tutorials/index.php?article=82 will usually help identify PHP errors, sometimes the problem is a little more elusive, and that's usually when files are incomplete or empty on the server. Also, the logging can only happen when the folder for logging (ie the yoursite/cache/ folder in v1.3.x) is not writable by apache/php.

Hello

Thanks for replying again...

I've read what you just typed but is there any way to try find out what it is or do I just have to stick with the standard Paypal and not install express? As the Standard version works on my site.

Thank you

I was implying that you may have damaged PHP files on your server, and you need to audit them all to fix whatever is broken.

I was also implying that maybe you're not seeing debug logs because the server can't write them due to permission problems.
And I was also implying that maybe you have other addons installed that might be conflicting.

I can't give you a definitive "do this to fix it" instruction because I can't replicate the problem you're describing. We would never have released the software if it was doing that to us when we wrote it and tested it.
Thus, I'm giving you suggestions on things you can do to diagnose and fix the problem yourself, by directing you to common causes of odd behavior.
