Hi, I just upgraded to 188.8.131.52 using Magento connect from version 1.6.2.
The upgrade went fine, site still functions (sigh of relief).
In the admin product pricing section, the group pricing options are not displaying (see attached). Strangely when i try to add a tier price I get an internal server error.
I have cleared the cache after the upgrade, reindexed all, restarted apache to clear apc cache, restarted the server in desperation. No group pricing.
On another site i upgraded via shell, and the group pricing came up fine.
Am i missing something?
