I had the EXACT same problem with Simple Catch pro…but a year later! I hope I can get a response to fix this.
– http://www.gordonatkinson.com.au
I installed the Simple Catch Pro theme using the simple instructions (like any other theme, via Install Themes in wordpress admin area).
At: Appearance/Install themes/Upload/Activate
Once I hit ‘activate’, my whole live site disappeared – a completely blank page with no error message.
Please help, client is not happy…I have reverted the site to the free version so that my client still has content!!
Thanks
