*the GMT time you saw the error
*the page where you saw the error
This is how you can delete the corrupted content:
1. Open the page without any content using by adding &noload=all to the URL of the menu page.
Example: beds24.com/control2.php?pagetype=bookingpagedesigncontent&noload=all will open SETTINGS-> BOOKING PAGE - > PAGEDESIGN - > CONTENT with all content removed.
The settings will be empty so you can enter your valid content and save.
Note: this will clear all settings on the page.
If you know the language which has the problem you can specify to only not load it using the 2 char language code like this (for English)
beds24.com/control2.php?pagetype=bookingpagedesigncontent&noload=en
