Troubleshooting

Browse button is missing or not functioning properly

• Since IMCE inserts the required javascript file into the closure of your theme, you must be sure that your theme supports closure and displays it correctly.
  In phptemplate themes like bluemarine or garland the closure variable is $closure that is usually printed at the end of the page(page.tpl.php). In case of a missing closure try printing theme('closure') or $closure just before the closing </body> tag.
• There may be a conflict with another javascript code. Check if the browser throws any javascript errors. Report this to forums or issue queue.

Directory related errors

• IMCE directory paths must be relative to drupal's file system path that is usually files. Therefore, to use the folder files/foo just specify foo.
• If you are using a manually(ftp etc.) created folder, PHP may not have read/write access to that folder. Try changing the folder permissions to chmod 0777 to allow PHP has full access to it.

Images disappear (on preview or after node submission)

• This is probably because of your default input format not allowing <img> tag. Select Full HTML as default or add <img> tag to allowed html tags for your default input format.

If you have another issue with IMCE, first of all, you should seek for a solution in the forum page and issue page. In case you can't find any answer and think it is a new issue, post it to issue queue providing detailed information.
