Hi.
The problem is similar to this: https://www.joomshaper.com/forum/question/6079
Joomla updated.
Helix 2.0.4.
I thought there was a problem with Helix 2.0.3 and 2.0.4 (no problem with 2.0.2), but during my tests I found that the problem is with Sp Page Builder 3.7.14!
No problem with Helix!
It seems to me that the error page is not loaded. (The html code inside the page is different, it's not the usual code for basic error page).
Can you fix it?
Or what can I do for fix it?
Same problem with other my websites.
Thank you.
