TypeError: Unsupported operand types: bool + string in Drupal\spammaster\Form\SpamMasterSettingsForm->buildForm() (line 689 of modules/contrib/spammaster/src/Form/SpamMasterSettingsForm.php)

Hi tekncat,

Thanks for reporting. Yes I see the + typo... corrected in version 2.45 that should come out later this week.

Also please login to spammaster.org to check all your licenses. Use 1 single unique license per website, please don't use same license in 2 or more sites. That will eventually throw a MALFUNCTION_6.

Thanks again,

Yes we also figured out the license thing and made sure that we are using a different license key for each site.

I could also see various ways this code could be refactored to shorten and simplify it, so if you're interested I could create a separate issue for that and commit some changes for consideration. It would help make the code more maintainable in the long run.

Thanks for taking a look Teknocat, please do.

Fixed in version 2.45
