Recurrent blank page bug

  • Hi,
    I run a wordpress website since a year and everything was right back few months ago but a recurrent bug came and that’s a bit annoying.
    Several times / week, all my pages become blank and the only way to fix that is to restore “Themes” using UpdraftPlus.
    So I was thinking the problem came from a corrupted file on the theme so I downloaded an instance of the theme when the site is working and another one when my pages are blank.
    I checked the diff between those 2 directories and… No differences at all. ??
    I activated PHP errors and wp-debug but it shows nothing.

    So I don’t know what to do, since few weeks I restore with updraft+ all day and that’s really boring ??
    Infortunately I can’t provide an example url because it’s actually corrected.

    EDIT: I didn’t precised that memory limit is set to 128M

    A blank white page means that PHP is crashing. This problem can be caused by a variety of issues, including:
    (1) Bad theme
    (2) Bad plugin
    (3) Bad install/upgrade
    (4) you exhausted the memory limit
    (5) It could also mean that there is an issue with your web hosting server.
    – 1 and 2 are more common (typically due to a function conflict introduced by a plugin or theme).
    – Since the problem can be caused by any number of things, check the error logs on your server for a more specific error message. If you need help locating them, ask your hosting provider to help you with that.
