This error occurs e.g. when a file-name contains an umlaut. By removing the umlaut this can fix this issue. However, if it doesn't check the other posted solutions in this entry.


I've got this error since some weeks, when I try to create a link to a file or folder inside RTE. Links to email or pages work fine. I had that problem with 6.2 and now after upgrade also with 7.6.15.

I noticed this issue when RTE had an incorrect link:

<link ../fileadmin/user_upload/documents/myhomeplan.pdf>

TYPO3 specifically reported that the file path is incorrect and that ".." and "//" are not allowed in the begining of file path.

This happened for us after we migrated from 4.5.x to 4.6.x.

Table that was affected: "tt_content"

Field where issue was noticed: "bodytext"

FIX: "remove the invalid character manually using DB"

Other possible places where this issue can be noticed:

  • Can affect: Any table, ex: news, tt_news etc...
  • Sometimes, we may even get into this situation when the file in question has been renamed/moved/missing.


Sadly when this issue happens, RTE failed to load. So, the only option I had was to correct the path directly in the DB using "phpmyadmin".

In my case it was "tt_content" table and the field that had isue was "bodytext"


I got this error when upgrading from 4.5 to 6.2 with the uprade wizard.

I ran a DB check and it solved the prblem for me. I then restarted the wizard and could go forward.


I also got this error when upgrading from 4.5 to 6.2 (starting from a 4.3 but not relevent)

In this case I recommend to perform a manual update of the reference index in the 4.5 context. Then look in the reference index for occurrences of ".." and "//" when @softref_key = 'typolink_tag' AND ref_table = '_FILE'@. It will give you the pattern to match. Typical patterns are "../fileadmin" or "uploads/tx_extension//filename.ext". The first pattern need correction in the original field too. The second needs correction in the extension tca. I also encountered links like "../?id=" but these are not related by it could be good to include (in tt_content.bodytext). After the changes, re-run the refindex update and you can go back updating to 6.2 If the issue is encountered while running the update wizards, make sure the maybe created file storage using the invalid "../" path is in deleted state.
