I was just curious to understand why Katharina would not want to have links in her posts. If she does not want to explain it then that is fine. All she had to do is say so.

Here is a query that will change http to h**p in every post. Please backup your database before running.

UPDATE post SET pagetext = REPLACE(pagetext, 'http', 'h**p')

Note the post_parsed table will still cache existing posts, so it will appear that no change have been made. You need to run Rebuild Post Cache for the change to take effect.

admin cp -> Import & Maintenance -> Update Counters -> Rebuild Post Cache
