Hi Ammalgam,
Please note that the Plus support forum can be found here – https://simplesharebuttons.com/forums/forum/simple-share-buttons-plus/
Sorry to hear you experienced issues. There are over 1,000 active installs and this is the first big error report, so this must somehow be specific to you.
Therefore if you could please open a support topic there with a link you your site I’ll review your current set up and let you know what settings will need to be applied to end up with a similar setup.
Any cache or CDN in place may have been the cause of issues if you have these enabled, please specify in your topic what you mean by everything was broken – was the site itself affected or just the buttons for example?
You can create an account here for the support forum if you don’t already have one – https://simplesharebuttons.com/wp-login.php?action=register
If you’d like me to get the upgrade in place for you, after creating your topic please provide FTP and WP Admin login details using a private reply or email [email protected].
Speak soon,
David
