Why is a blank PHP page displayed on page load?

Question

PHP

I had such a problem with one site, I go to the site and start clicking on the links - sometimes the page is displayed normally, and sometimes it just opens a white page (empty), if you press Ctrl + U to see the HTML code, then it's just empty. And sometimes you have to press F5 several times to display the page. I look at the Apache server logs - but it is empty there, this error is not displayed in the logs in any way. Moreover, the server where the site is located is very powerful (Top Core i7 + 32GB RAM DDR3 2400Mhz) What should I do? How to get rid of such a glitch?

Answer 1

Look at the errors in the Apache logs. What error code does the server return on a blank page? Wangyu 500 - in this case, an error message should appear in the log.
