Upgrade Form Builder - http 500 error

Hello,

I upgraded form builder to v2.6.1 and looks like it upgraded fine but I am getting 500 error when going to Modules > Form Builder. I can see the homepage but when I try to do anything(Add Form, Settings, Edit Form, View), I'm getting the 500 error.

No Issues on Site Status
I can go to Developer >  Modules and Edit Form Builder without any issues
I looked at the directory extensions/com.fastspot.form-builder and all the files seem to be there.

This is the url when going to Settings.
admin/com.fastspot.form-builder*btx-form-builder/settings/

Any suggestions on what could be wrong?

Thanks

Doon

Figured out the issue, we had php version 5.5 and form builder needs at least 7.

Glad you figured it out! I think BigTree 4.5 requires PHP 7.4 if you're using AWS dependencies. I'm not sure which part of Form Builder in particular is requiring PHP 7 though.

The null coalescing operator (??), which is a new feature with 7.

Ah, yes that's used very frequently now in BigTree 4.5 to avoid all the warnings on undefined variables smile
