Drupal:After installing boost module, images are not uploaded in files/imagecache

Title explains it pretty much. After installing Boost module, i have troubles with uploadi开发者_如何转开发ng images. I can upload them, but only thumbnails are saved. Big image in sites/default/files/imagecache is not created. I tried to play with permissions, but didnt work. I have no idea where the problem is. What did boost module change that images cant be uploaded? What shall I do?

This is critical. I tried to uninstall the module, but the problem still persists.

Boost is not the issue here. If the module is uninstalled and you still have a problem then it's not Boost. To be 100% sure make sure to get rid of the htaccess rules. I have not idea why people like to blame boost but it does happen.
