Breaking: #83081 - Removed configuration option BE/fileExtensions/webspace

See forge#83081


The file extensions which are allowed to be uploaded, which were previously available under $TYPO3_CONF_VARS[BE][fileExtensions][webspace] called allow and deny have been removed.


  • Using the old configuration option names will result in a PHP notice.

  • In Import/Export when uploading files fileDenyPattern is used instead of allow and deny

  • When using BasicFileUtility directly, only fileDenyPattern is used

Affected Installations

TYPO3 installations which have set this option in LocalConfiguration.php previously, or extensions which still use the old configuration option names.


Use fileDenyPattern which is used consistently throughout the core to deny specific file extensions.
