I had some issue after upgrade the Redirection plugin to 4.0. Redirections were not working anymore and I was unable to add some (with ugly “something went wrong” and a 500 API error code). It turned out that was because an incompatibility of the database upgrade with the SQLite Integration plugin : the database upgrade uses many keywords unknown to SQLite (“AFTER” keyword in ALTER TABLE, “SUBSTRING_INDEX” and “LEFT” functions)

To fix this I fixed the “AFTER” keyword in the SQLite Integration plugin. Here is the corresponding (very simple) Pull Request : https://github.com/aaemnnosttv/wp-sqlite-integration/pull/2

To force the Redirection plugin to update the database I updated the “redirection_options” in the table “wp_options”. In the option_value field you will find the serialized options, and in it the snippet “ s:8:"database";s:3:"4.0" ” (my database was in version 4.0) ; I updated to the version 2.0 (“ s:8:"database";s:3:"2.0" “) to be sure to get all the database evolutions, but you may start after that.

As the replacement of the missing SQLite functions was more difficult to handle, I updated the Redirection SQL code to update to the new database and executed it manually in my SQLite database :

Redirection is working fine now, handles redirections properly and let me adds some more again !
