Page blank when updating membership plan

Hello,
I have the latest Mwmbership Pro (2.7.0) and Joomla 2.6.4 - I wanted to add a renewal option for a membership plan so added 1 year at 135.00 and pressed Save. The screen went blank. When I refreshed the action hadn't been completed. I checked the error log and also had error checking set to Maximum but no error is showing.

Hi Dan

This issue is strange to me. Maybe it conflicts with other extension (do you also use OS Property on the same site) ?

Please submit a support ticket sending us super admin account of your site. We are going to check to see why the issue happens and get it sorted

Hi
I don't use OS Property on this site. I checked with the webhosts and there are no errors recorded when the screen is blank at the end of this action.

To recreate I was adding a renewal option of 1 Year at £135 to a subscription plan

Thanks

Hi Dan

Please help submitting a support ticket. I will have my developer look at it to see why the error happens and get it sorted

Tuan
