If you are upgrading from uCash & uShop 0.93 or 0.95 and experience those errors, run these 2 queries:
[sql]ALTER TABLE user CHANGE `uttpoints` `ucash` DECIMAL(20, 2) DEFAULT '0' NOT NULL;
ALTER TABLE forum
CHANGE `uttpoints_perthread` `ucash_perthread` varchar(20) DEFAULT '1' NOT NULL,
CHANGE `uttpoints_perreply` `ucash_perreply` varchar(20) DEFAULT '1' NOT NULL,
CHANGE `uttpoints_perview` `ucash_perview` varchar(20) DEFAULT '1' NOT NULL;[/sql]
It appears that I made a mistake in the queries in the product file. I'll update the zip in a minute.
Sorry for the error.
EDIT: The zip file is now updated to fix the problem. Run those two queries if you have already installed 1.1.1.
