I installed Joomla 3.9 and have a blank backend page now (payplans). All other works! Terrible!

Its a problem with joomla 3.9 and payplans, the only thing you can do, its downgrade joomla or install a previous version with akeeba backup, I hope you have a backup from your site.

I work Offline for now, so its doesnt matter for me this error for now, If you work offline You can install payplans beta I do that I work and test. With payplans 4 beta this error its no happend.

Have a nice day.

I am awaiting an answer from stackideas! Yes we have a backup. Database has all data from payplans, Frontend works with payplans. Dont expect a big problem. Only backend is not possible to use. Thanks. Have a nice day, too

Hello,

To resolve this issue for now, do the below mentioned changes.
1. Go to root/components/com_payplans/xiframework/base/helper/toolbar.php, near line no. 11 find below mentioned code.

require_once JPATH_ADMINISTRATOR.DS."includes".DS."toolbar.php";

Hello Tatiana,

To resolve export app related warning, find attached kit of export app.
Install it and see if still issue persist.

By the way, it looks like your payplans subscription has expired and in order for you to continue requesting for support, you will need an active subscription. If you have already renewed, please let us know so that we can correct this for your account.

Thank you for understanding.

Dear Manisha!

Many thanks for that. We are long term customers. For now, we are waiting for the new PP4. In the case of Joomla I should update this. I hope you understand that. We like PayPlans. Excellent.

Hello Tatiana,

Thank you for your kind words .
Currently we don't have the exact release date for Payplan 4.0 stable version but we are looking at end of November.
