Thread:Project:Support desk/Fatal error: Cannot redeclare class HttpError in / my dir /deployment/io/DF HttpDownload.php on line 460/reply

What do you want to tell us with the information about the repositories and the bundles?

You say you cannot access the page Special:CheckInstallation on your wiki, because then you get the error "Fatal error: Cannot redeclare class HttpError". Is that correct?

The file DF_HttpDownload.php, in which you get this error, does not come from MediaWiki. According to Google it seems to come from SMW instead. I don't know how to put these information together... Where do you have the files in the folder io/ from (especially the file DF_HttpDownload.php)? Why is it called when you log in to MediaWiki, although it does not belong to MediaWiki?
