[Drupal] How to resolve Drupal issues while Configuring IMCE to Ckeditor

We had a requirement by one of our Drupal client of configuring IMCE to CKeditor instead of ckfinder. I have faced the following issues after changing the file browser type as IMCE in CKeditor.

Lets go through some issue faced by IMCE install and its bug fixings

1.IMCE image upload permission issue

The real issue is due to file permissions. When we uploads a file, it gets saved to a temp directory. When that file then gets moved does not inherit the destination folder permissions.
So,check for the folder permissions of both the temp and destination folder.

2.Page not found issue found on 'Browse server' click

1. Check for the path settings -/admin/settings/imce whether user role is assigned to the profile created.
2. Also see whether the pathauto enabled prior to Ckeditor and IMCE module.If so Unistall the pathauto module and install CKeditor and IMCE prior to pathauto.Next enabled the pathauto module Again

3.Issue with link and unlink icons do not display and the majority of the icons are displayed in black and white not colour.

The unlink and link image will change on theme change.So we cant predict if it exits in the page.

1. Issue due to configuration setting for editor appearance theme change
2. fixed the Issue by changing the theme from Moono to Kama
