Hi,

I purchased the MailChimp extension, I entered the required values (Api KEY and List ID) but at the time of registration I get a page 500 error …
So I tried to activate WP_DEBUG and get the following message:

Fatal error: Uncaught Error: Class ‘UWP_MailChimp’ not found in /home/ygpsejgq/public_html/wp-content/plugins/uwp_mailchimp/includes/functions.php:12 Stack trace: #0 /home/ygpsejgq/public_html/wp-content/plugins/uwp_mailchimp/includes/functions.php(79): uwp_mailchimp_send_subscription(‘lorenzo974@gmai…’) #1 /home/ygpsejgq/public_html/wp-includes/class-wp-hook.php(286): uwp_mailchimp_subscribe_user(true, Array, ‘register’, 30) #2 /home/ygpsejgq/public_html/wp-includes/plugin.php(203): WP_Hook->apply_filters(true, Array) #3 /home/ygpsejgq/public_html/wp-content/plugins/userswp/includes/class-forms.php(370): apply_filters(‘uwp_after_extra…’, true, Array, ‘register’, 30) #4 /home/ygpsejgq/public_html/wp-content/plugins/userswp/includes/class-forms.php(51): UsersWP_Forms->process_register(Array, Array) #5 /home/ygpsejgq/public_html/wp-includes/class-wp-hook.php(286): UsersWP_Forms->handler(”) #6 /home/ygpsejgq/public_html/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(”, Array) #7 /home/ygpsejgq/public_html/w in /home/ygpsejgq/public_html/wp-content/plugins/uwp_mailchimp/includes/functions.php on line 12

I think there’s something that’s not working …
I am using WordPress 5.0.3

Can you solve?
Thank you

That’s very strange. Could you please provide a link and admin credentials and possibly FTP credentials too?

A developer will have a look as soon as possible.

Thank you,

I have the same problem but I can’t see any solution as most of the posts are marked private. How can I fix this problem?

Any help is much appreciated!

All the best,
Torsten

I think I have found the problem:

In line 103 of uwp_mailchimp.php the line:
```
if ( !class_exists( 'MailChimp' ) ) {
```
needs to be changed to:
```
if ( !class_exists( 'UWP_MailChimp' ) ) {
```
Then it works for me.

All the best,
Torsten

Hi,

It doesn’t need to check if the class exists for ‘UWP_MailChimp’ as only our add on will be using that class. We have put the condition to check if ‘MailChimp’ class exists or not because there might be other plugins using the same library which we are using so it may be possible they already defined that class. So you can now remove that condition and it should work fine.

We are working on changing settings interface for UsersWP and it’s add ons so we will release the changes asap after testing.

Regards,
Patrik
