Hi there,
Many apologies for the delay in responding, please note that as you have the Plus version you are entitled to enhanced support, where we aim to respond to support requests in around 6 hours.
The forum can be found here – https://simplesharebuttons.com/forums/forum/simple-share-buttons-plus/ – or you can email [email protected] with your license key.
The issue you’ve come across is related to running old PHP versions. Simple Share Buttons Plus only supports 5.3+, you can read more about why here – https://docs.simplesharebuttons.com/plus/requirements/#why-not-php-5-2
Most hosts are happy to upgrade your PHP and often do pretty quickly, but if you have any issues upgrading just let support know via the support channels I mentioned above.
Thanks,
David
