Hi,

I'm not sure why but all the .PHP pages on my online shop www.thetahealth.co.za have suddenly stopped working and are not loading in the browser. Even the Product Search and Blog do not work. 

The .HTML pages load in the browser fine but not .PHP pages.

I had my .PHP setting set at 7.3.25 the highest my hosting company has and dropped it down to 7.2.34 but still not working on either. I have put it back up to the highest again.

You can test a .PHP page here:http://www.thetahealth.co.za/natural-alternative-health-practitioners.php

You can test a .HTML page here:http://www.thetahealth.co.za/human-growth-hormone-supplements.html

This is an error I get on the browser after a while for the .PHP page: 504 Gateway Time-out

This is an error I get in my website's log files. I'm not sure if this is relevant or not: 1299512#0: *3564947 upstream timed out (110: Connection timed out) while reading response header from upstream

Any assistance needed urgently as my online shop is currently broken and losing sales.

Thanks,

Nigel.
