Most options on this page have one option that you may set, Number of X to process per cycle. This is the number of records that are processed on one page. Generally, the higher this number is, the faster the process will complete; however, the higher the chance of your browser timing out and the process not completing. In most cases, the default value should suffice.
The following functions are available:
- Update User Titles
This will update all users’ user titles. Users with custom titles will not be affected.
Run this if you have changed the user title ladder and wish to see the changes reflected immediately for all users. - Rebuild Thread Information
This will rebuild thread counters such as replies and attachment counts. Also it will rebuild the cached first and last post information of a thread.
Run this if you have pruned specific posts from many threads or changed a user name and wish to see the change in the last post information of each thread. - Rebuild Forum Information
This will rebuild the post and thread count in each forum based on the number of posts/threads actually in the database. Additionally, it will rebuild the last post information for each forum.
Run this if you have mass-deleted a lot of threads or posts or have renamed a user and wish to see the changes reflected in the last post information of the forum. You may need to run Rebuild Thread Information first, though! - Fix Broken User Profiles
This will fix any users that are missing records in the userfield or usertextfield tables. This generally only happens because of outside programs incorrectly interfacing with vBulletin.
You will generally not need to run this function unless you use an outside program to register users and it does not properly register this. - Rebuild Search Index
This will rebuild the index used to perform searches. This will allow you to take advantage of any improvements to the indexing algorithm or implement any changes to the indexing options on older posts.
Run this after a major upgrade (such as vBulletin 2 to vBulletin 3) or if you wish to apply changes to the indexing options to all posts.Note:The search index is automatically built for each post as it is posted. This is simply a batch function. If you have done a major upgrade, your search index will have been deleted. Your search engine will not function fully until the index has been rebuilt. - Rebuild Post CacheNote:This option will not be displayed if you have not enabled post caching.
This will rebuild cached post data.
Run this if you have changed a BB code template, BB code, or smilie and the changes are not being displayed on recent posts. - Rebuild Statistics
This will rebuild your board statistics (user registrations, threads, posts, and active users per day) from the first post on your board. Statistics will automatically be generated for new days.
Run this if you have done a major upgrade. - Rebuild Similar Threads
This will rebuild the similar thread information for each thread. This allows the similar thread function to find threads that have been posted since the thread in question originally was.
Run this if you have changed the similar thread thresholds or wish to have the similar threads function display newer threads as well.Note:This will rebuild similar threads regardless of whether they are enabled. They must be enabled in order to be displayed in a thread. - Delete Duplicate Threads
This will remove all but one copy of threads that appear to have duplicates (same title, poster, time, and forum).
This rarely needs to be run; only run it if you see duplicate threads in your forums. The most common cause for this is multiple imports of the same data. - Rebuild Attachment Thumbnails
This will rebuild the thumbnails of image attachments.
Run this if you did not (or could not) have thumbnails enabled in the past but wish to now or have changed thumbnail dimensions. - Rebuild User Reputation
This will rebuild your user reputation scores based on the information in the database and the new reputation base specified here.
Run this if you want to remove any custom reputations and specify a new reputation base. - Update User Names
This will update all cached user names in the database.
Run this if you have manually changed a user name. - Update Post Counts
This will update all users’ post counts based on the actual contents of the database. If you have pruned or manually changed post counts, this function will likely lower your users’ post counts.
Run this if you wish to regenerate post counts with your current data. - Rebuild Styles
This will rebuild your style information. Additionally, it can check for styles without a parent (pre-vBulletin 3 styles) to ensure they work properly and renumber your templates in the database. The latter is simply aesthetic; there is no advantage to having templates that begin at 1.
Run this if you have done a major upgrade or have edited your templates or styles manually. - Remove Orphan Threads
This will search for any threads in non-existent forums and remove them. This is helpful if you deleted a forum and the process timed out before completing.
- Remove Orphan Posts
This will search for any posts in non-existent threads and remove them. This will generally not be needed, but could be helpful if your data was corrupted somehow.
