Error 500

[amallory]

Hello,

When I activate Quform w/ WP 4.9.8, I get a server error 500 – – I then have to rename the quform plugin folder in order to access the site again.

I have deactivated all other plugins and changed the theme to the default 2017 theme but am still getting the same error.

It is quite odd because I have never had this issue with quform and have it running on multiple other sites.

Thx in advance

Also tried various php versions — currently set to 7.2 w/ current version of quform (just downloaded)

caused by the PHP fatal error below for “Uncaught InvalidArgumentException”.

Below is the line from Factory.php that is throwing the InvalidArgumentException.
====
if ( ! $element instanceof Quform_Element) {
throw new InvalidArgumentException(sprintf(“Method not found to create element of type ‘%s'”, $type));
}

That sounds very likely. I got things working again by installing an older (1.x) version of quform.

So should I still remove the form from the database and start over? Or do you think I can upgrade to v2 and import?

Thx

I removed the forms using phpMyAdmin, then installed the current version of Quform — then migrated my forms. Lastly, removed the old version of Quform.

Everything working properly now.

Thx
