I just migrated some of my sites and everything is working fine. No problems from any of the plugins. When I get time I’ll list all the plugins and theme that’s in use and working. I changed my theme’s functions.php file so it now says Powered by ClassicPress. I’m not sure what I can do but I’m going to try to find something I can do help on the project.
This is just an FYI for anyone using the migration plugin. For people that’s been doing this a while it won’t mean much. But for someone new it might help (I hope a lot of people switch). I just finished migrating 7 of my web sites. 5 went off without a hitch, but 2 didn’t go so well. I got a migration failed warning and then if you clicked on anything you get a plain white page. But don’t panic. You can try what I did and if it works for you like it did for me all will be good.
Go to the Installing ClassicPress page https://docs.classicpress.net/installing-classicpress/#migrating-to-classicpress-without-using-the-plugin follow the instructions under “Migrating to ClassicPress without using the plugin”. When you upload using Filezilla or what ever you use there will probably be a few files that fail to upload. You will probably have to delete those files on the server using your ftp program and then upload the files again and they should be successful. Now try your site and it should be working. If not, ask for help here. I’m sure someone more knowledable than I will be glad to help you.
