I upgraded the plugin via DASHBOARD > UPDATES and received error “From version 3 MaxButtons requires at least PHP 5.3 You are running : 5.2.17”
All buttons on site missing just showed shortcode text.
My cPanel says I’m running “PHP version 5.4.24”
Plugin deactivated and activated didn’t fix the problem.
Not super techie in this area so didn’t want to waste time.
I downloaded the old version of the plugin (link on page 1 of this discussion)
Unzipped it on my harddrive
Deactivated the plugin in my WordPress Dashboard
Opened FTP /wp-content/plugins and renamed existing maxbuttons folder then copied the old version ‘maxbuttons’ folder from my harddrive into ftp.
Activated the plugin in my WordPress Dashboard
and buttons back to how they were working before.
Error still displays, but at least the buttons are back to working normally.
Note to self – don’t update plugin until bugs are ironed out.
