[TYPO3-english] 302 redirect when invoking file browser

[Graham Knight]

Hi,

On one system I manage I have the following problem (TYPO3 6.2.13, PHP5.6.13 ):

When editing a Text+Images CE I select the Images tab and click "Add Image". A new window pops up but, after a pause, the website home page appears in it instead of the file browser.

I have looked at a packet trace and I see:

GET /typo3/browser.php?mode=file&bparams=|||gif,jpg,jpeg,tif,tiff,bmp,pcx,tga,png,pdf,ai|data-5-tt_content-93-image-sys_file_reference|inline.checkUniqueElement||inline.importElement HTTP/1.1\r\n

With response:

HTTP/1.1 302 Found\r\n and Location http://{domain name of the website}/\r\n

Unfortunately I have no clue as to where this redirect comes from.

I cannot see anything relevant in TYPO3 logs. Unfortunately I do not have access to the Apache error log. I have a .htaccess file in my document root (see below). I have tried clearing caches but with no result.

I used to see this problem intermittently in the past but it is now persistent.

Has anyone seen something similar or can suggest a debugging strategy?

Many thanks.

Graham
