Under normal circumstances, +this would cause a huge security risk, but because we are running +HTML through HTML Purifier, output is guaranteed to be XSS free and +standards-compliant. + +This mod requires HTML input, and previous markup languages need to be +converted accordingly. Thus, it is vital that you create a 'migrate.php' +file that works with your installation. If you're using the built-in +BBCode formatting, simply move migrate.bbcode.php to that place; for +other markup languages, consult said file for instructions on how +to adapt it to your needs. + + -- NOTE ------------------------------------------------- + You can also run this module in parallel with another + formatting module; this module attempts to place itself + at the end of the filtering chain. However, if any + previous modules produce insecure HTML (for instance, + a JavaScript email obfuscator) they will get cleaned. + +This module will not work if 'migrate.php' is not created, and an improperly +made migration file may *CORRUPT* Phorum, so please take your time to +do this correctly. It should go without saying to *BACKUP YOUR DATABASE* +before attempting anything here. If no migration is necessary, you can +simply create a blank migrate.php file.
