Hello,

i've just purchased 2 licences for remository extensions for joomsef.

as i installed it on one of the site i get the following error message : ERROR_DEFAULT_404

any idea to fixe this ?

Laurent

a little up !

That seems it is trying to call the default 404 message, but the translation is missing.
Maybe some files were not installed correctly? (e.g. to administrator/languages)

As regards the reason for 404, might be that the cache was not cleaned after the extenison install?
Please, try to be more specific about the error and when it occures.
