Hi. Recently posts and pages on my website AynRand.no have begun to show the light green background color in the white box where there’s just supposed to be black text and images. The erroneous background color has a very peculiar pattern. It starts out filling the width of the box, before gradually becoming slimmer down to the middle of the text, before widening out to the bottom again—kind of like a time glass form.
The error occurs on the Google Chrome browser on a Samsung Galaxy S9 with Android 9. I have not been able to reproduce the error on desktop emulations of mobile screen sizes. I have disabled all plugins and cleaned the cache, but the problem still remained, so it must be due to the theme itself (or some of my custom CSS modifications to it).
What should I do to solve this issue?
