I disabled plugins and deleted the plugins folder before I started the upgrade.
The plugins should have been
uninstalled and deleted.
Keep this in mind as you make your repairs. The entries can be deleted from the db or if you completely downgrade, then uninstall, etc.
Your choices, in my opinion are to recreate the db as that thread directs you to.
Manually editing the database will be a time-consuming task. In fact you need to run the queries in sql/update.sql - just make sure to replace the prefix CPG_ with your custom table prefix cpg148_. Subsequently, the database query you need to run would be as in the attached file. You can do a copy-paste job from the file right into the query field of phpMyAdmin.

Or use your backup db.
- remove the plugin entries after you restore it
- check it for errors
- make sure that you have a clean, complete upload of cpg 1.5.12 on your server
- if your anycontent.php file has code, links, etc in it, use the cpg anycontent.php file or edit
the db entry in Config to temporarily remove any influence
- run update.php, look for errors
If you have your albums folder, config.inc.php, and anycontent.php backed up, then you should also be able to ask your host for some assistance too
I am not very experienced with your problem, so that is the best that I can offer. With backups intact you should be fine, no matter what you try.
