thanks alot shashank for reply! but i am using open erp online using internet and not using its source code i mean only install open erp and its database. it was working fine but now my apps are not showing i have reinstall it 2 times but same error please correct me and give me any advice.

"but i am using open erp online using internet"!!!!!! Are u using runbot openerp? http://runbot.openerp.com

can u give me brief description wat excatly u doing. so that i can figure out wat error u made

i have install open erp v 7 with its database and just running it on browser with local host 8069. it was running fine but not now. plz tell me where is the problem.

There would be 3 possiblities->

1. There might be issues in webclient(web addons) as ur erp takes too much time to load.

2. some packages might have corrupted such as zsi,werkzeug etc.

solution->

1. Install latest openerp code from nigty erp. I have installed it and working fine on my local system.

2. Upgrade /update/reinstall your python packages required for openerp.
