When trying to add or modify existing content, a long error message appears in the website’s back office. I do remember seeing a similar issue already being raised in the forum, but am not sure whether there is any way to fix it?
Can I just add the content as usual or am I running a risk of breaking the website?
We are aware of this issue. It is unfortunately still affecting a few websites, though you are perfectly fine creating new content. The reason why it is thrown is actually because a variable is empty in the first place. We are planning yet another upgrade sometime this week which will hopefully alleviate the issue altogether.
