I get the following error when outputting a field of type text or textarea in the frontend.

for all. II found the cause of the error. If you enter viewing->Layout->Clean values->unsafe HTML in the configuration of the field then the error appear.

oh great ! sorry for no replay ... thanks for share solution

... hello,

thanks for the hint, but this doesn't work for me.

I changed field definitions of the suspicious text and text area fields to "unsafe HTML", also tried "all HTML", but no difference.

On the other hand, saving items of other content types with different field sets work well, so it should be something with field definitions.

I also noticed that hitting "apply" instead of "save" button shows up a progress bar that never finishes.

Any ideas?

(J! 4.1.5, FC 4.0.2, php 7.4.30)

... OK, seems I found something that works in my case, the following settings for textarea fields:

(1) serverside valuation settings: one of the "TEXT..". options
(FIELD Type specific configuration -> edit -> values).

and

(2) NO cleanup of HTML values in layout view
(FIELD Type specific configuration -> view -> layout).


Regards

thanks for ssharing solution
