haihoang202 on "[Plugin: WordPress Button Plugin MaxButtons] Update from 2.9 to 5.5 Buttons disappear"

I updated my plugin from 2.9 to 5.5 and the button disappear.
I tried deactivate and activate again, I also deleted __v3 table in the database and reactivate again.
But none of that works!

Please help!

Thank you,

Hi,

Are you using the PRO version or the free version? There was never a free version with that version number. To upgrade PRO you'll need to get the plugin from our website (http://www.maxbuttons.com). Updating a PRO version with a free version will not work, so maybe that's the issue here.

Thanks for the reply,
I installed both version, but using PRO version 5.5 now
What could fix that ?
