Please enable debug as shown at https://kb.mailwizz.com/articles/enable-debugging/ and then reload that page again, then scroll down till you see the error (highlighted in red) and take a screenshot out of it and add it here.

I had this same issue now with the latest Mailwizz version, it was caused by the RANDOM_CONTENT tag not being able to render numbers randomly (it used to be able to in earlier versions)

@rita you mean something like this triggers it: [RANDOM_CONTENT: 1|2|3|4|5] ?

Correct

@rita - I just tried now and I cannot reproduce it:

$content = 'This is some random content "[RANDOM_CONTENT: 1|2|3|4|5]" and it should work just fine!';

echo CampaignHelper::applyRandomContentTag($content) . PHP_EOL;

And I got:

cristi@Serbans-MacBook-Pro /tmp % php rnd.php     
This is some random content "2" and it should work just fine!
cristi@Serbans-MacBook-Pro /tmp % php rnd.php
This is some random content "5" and it should work just fine!
cristi@Serbans-MacBook-Pro /tmp % php rnd.php
This is some random content "3" and it should work just fine!

Can you please give me more details?
