Hello,
I just tested Membership 2 on freshly updated WordPress 4.6 and I cannot replicated that problem. There was no problem with M2 installation.
After checking your WordPress plugin dowload page and checking its features, it clearly states that it’s compatible up to: 4.5.3, not the 4.6. version https://snag.gy/wt0QNK.jpg
That information is hardcoded in plugin readme.txt file and last release was done with previous version of the WP, so that why it doesn’t show 4.6 there. Information will be updated with next release but we do test our plugins with new WP versions and M2 works with WP 4.6.
When I go ahead and update, this is the msg I get:
https://snag.gy/tBgdq2.jpg. Then and it gets stuck and never updates.
Can you update plugin manually through FTP? This one shows that there is problem with updating process and reasons for that can be different – from plugin conflict to problems with memory. From what previous version are you updating M2?
Matt, it would be better if you create your own thread about that issue and if you can, please post bigger images – I cannot see anything here https://s12.postimg.io/9nt8ld2gp/screenshot_Thu_Aug_25_22_41_14.png
