Hello,
Thanks for your support.
I have the issue resolved and it was not related to upgrading EasyBlog
I have detailed what caused the issue as it maybe of use to you should someone else report the same occurring to them.
I had the attachments extension installed which is available on joomla extensions directory. When I uninstalled it the following occurred (including the editor not working in easyblog)
1: Frontend of site index.php loaded as blank page.
2: Could not access Global administration
3: Could not edit articles in joomla administration (blank page)
SOLUTION
The attachments extension does not uninstall properly. Numerous plugins remain related to the editor in the administration. They must be uninstalled manually in the extensions manager.
Once uninstalled the site loaded again, Global administration was accessible, articles editor worked and most importantly the editor in Easyblog worked.
Thanks,
Have a good day.
John O Connor.
