OC Upgrade

Looking for some help. Will pay for service since I dont have the time right now to trace it however I will need to know what was changed so that I can replicate the issue and fix the issue. Basically I might need to clear the account and start fresh with the migration process for documentation purposes.

Theres two issues:

1. See the post here: viewtopic.php?f=199&t=202000&view=unread#unread
I was able to fix some of the issues but I'm having a problem with the theme. Under settings for Theme, it displays "heading_title". I have no way to change it to the default theme. I save the settings but I'm still getting a "Error: A theme has not been assigned to this store!". Now if I go to the database and the settings table, then change the config_theme from "theme_default" to "default", then I'm able to see the front page and it loads without error. Now when I go back to the admin area and change the store settings, then save, it reverts back to "theme_default" this renders the front end useless with the "Error: A theme has not been assigned to this store!" error. It may me a language issue as stated in the post link above.

2. Now when I run the "Move Storage" from the pop screen upon logging in the back end, I get these errors:

From the front end (domain.com):

Notice: Use of undefined constant DIR_CACHE - assumed 'DIR_CACHE' in /home/account/public_html/system/library/cache/file.php on line 9Warning: Cannot modify header information - headers already sent by (output started at /home/account/public_html/system/framework.php:42) in /home/account/public_html/catalog/controller/startup/session.php on line 25Notice: Use of undefined constant DIR_CACHE - assumed 'DIR_CACHE' in /home/account/public_html/system/library/cache/file.php on line 25Notice: Use of undefined constant DIR_CACHE - assumed 'DIR_CACHE' in /home/account/public_html/system/library/cache/file.php on line 63Notice: Use of undefined constant DIR_CACHE - assumed 'DIR_CACHE' in /home/account/public_html/system/library/cache/file.php on line 47Warning: Cannot modify header information - headers already sent by (output started at /home/account/public_html/system/framework.php:42) in /home/account/public_html/catalog/controller/startup/startup.php on line 99Notice: Use of undefined constant DIR_CACHE - assumed 'DIR_CACHE' in /home/account/public_html/system/library/cache/file.php on line 25Warning: Cannot modify header information - headers already sent by (output started at /home/account/public_html/system/framework.php:42) in /home/account/public_html/catalog/controller/startup/startup.php on line 157Error: A theme has not been assigned to this store!

From the Admin login page (domain.com/admin):

Notice: Use of undefined constant DIR_CACHE - assumed 'DIR_CACHE' in /home/account/public_html/system/library/cache/file.php on line 9

From the admin backend (once logged in):

Notice: Use of undefined constant DIR_CACHE - assumed 'DIR_CACHE' in /home/account/public_html/system/library/cache/file.php on line 9Warning: Cannot modify header information - headers already sent by (output started at /home/account/public_html/system/framework.php:42) in /home/account/public_html/system/library/response.php on line 36

Please message me a quote so we can get started.

Finally got it fixed by Shivank Agrawal c/o Anaisys Technologies India!

Thanks.

How You Fix This Error

I was getting these errors as well. I think it's an issue not defining the cache folder when upgrading. I added this line to both config files and the errors went away.
