Front end is still working. But opening the homepage in SP gives a white screen. Nothing to edit. I installed new version of article.php which was a solution with 4.0.3, but this makes no difference.
I am using a one page layout with hardly any content!
I had 2 older duplicates of my homepage and they both work.
Could the problem be in one of the add-ons?
Any idea how to solve this?
