I'm rebuilding my current website using the Spirit Theme. I installed CalPress Pro calendar plug-in recommended by WPMU Dev (see https://premium.wpmudev.org/blog/best-wordpress-event-and-calendars-plugins-reviewed/); however, I'm now unable to access my Dashboard. Instead when I enter the following in my browser "http://wsbydesign.com.wsbydesign.com/wp-admin/" I receive the following error message:
Fatal error: Class 'WP_Screen' not found in /home4/kimcohen/public_html/wsbydesign.com/wp-content/plugins/calpress-pro/app/helper/class-calp-attends-list-table-helper.php on line 59
I realize that it's stating that the WP_Screen can't be found, but exactly what do I need to do to correct this. I've not been able to connect with CalPress Pro. It appears I'm not alone and many others who purchased the plug-in are experiencing the same frustrations in not obtaining support. I'd uninstall the plug-in completely, but I'm unsure how to do that since I'm totally locked out from my dashboard. I've attached a copy of the file in question for your review.
I'm hoping you'll be able to help me resolve this issue so I can continue working on my site.
I look forward to hearing from you.
