I can help you with the second issue.
First, make a copy of the bbPress folder and search for ‘bbp_get_forum_pagination_count‘ in Explorer.
If you don’t get any results at first, make sure you’ve turned on text search for .php files:
1) Open the bbPress folder:
ALT key -> Tools -> Folder options -> Search tab -> Always search file names and contents
2) Make sure that .php files are included in file content searches:
Windows Start menu -> Type ‘Indexing Options and press return -> Advanced -> File types -> php -> Index properties and File Contents -> On
The result of the search should be:
bbpress/includes/topics/template-tags.php
Now, locate the function ‘bbp_get_forum_pagination_count‘ and remove the ‘Viewing topic…’ code.
If you also want to rempove it from searches, please search for ‘bbp_get_search_pagination_count‘ and repeat the procedure.
I hope this helps!
Oh and if you also want to hide it in individual topics, just search for ‘bbp_get_topic_pagination_count‘.
