Undefined index on front end

There are more undefined indexes than just the one you posted unfortunately.

I’m also suffering from this error.

I have the same problem on https://fabriqueinnovpublique.fr/clermontmetropole/
Here is the error message:
Notice: Undefined index: enable_visitor_recognition in /home/fabriqz/www/wp-content/plugins/tawkto-live-chat/tawkto.php on line 341

Can everyone please confirm that the plugin was installed completely, all caches were cleared and there are no relevant messages in any error_log file?

The version 0.5.1 did not fix all of the undefined indexes mostly located in the validate_options function in tawkto.php line 109 and there is no check if the $customer_details variable in the /templates/widget.php line 5 exists (checking if null is not the same thing in PHP).

It doesn’t look like this forum is getting much attention from the developers, and the plugin’s readme file contains this:

tawk.to offers 24×7-365 live support, visit https://www.tawk.to and initiate a chat or send us an email at [email protected].

You may have better luck there, but please come back here and update with any progress.

Hi everyone!

The plugin’s been updated (0.5.2) addressing the undefined index issues on validate_options function and the checking of the $customer_details variable.

Hi again everyone! Can I mark this support thread as resolved?

Now I’m getting the following PHP Notices

• PHP Warning: Illegal string offset ‘enable_visitor_recognition’ in wordpress\wp-content\plugins\tawkto-live-chat\tawkto.php on line 264
• PHP Notice: Uninitialized string offset: 0 in wordpress\wp-content\plugins\tawkto-live-chat\tawkto.php on line 264

Hi @wplugged! The plugin’s been updated (0.5.3) fixing issues on enable_visitor_recognition.
