We really like your plugin and have been using it on multiple WP 4.6.1 multisite networks, but a serious problem has arisen.
Our server crashed multiple times recently and eventually two different developers identified a conflict between Strong Testimonials and your plugin Add Tags and Categories to Pages and Post Types.
After extensive research the cause of the conflict was determined to be due to the following:
**16 mins ago
“pre_get_posts should not be used to alter the query for single Page requests (page templates) because ‘is_page’, ‘is_singular’, ‘pagename’ and other properties (depending if pretty permalinks are used) are already set by the parse_query() method.”**
Can you provide and update to fix this so we can continue using and recommending your plugin?
