Hmm.
I have this value in upload_settings:
{"filestorage__core_Advertisements":1,"filestorage__core_Attachment":1,"filestorage__core_Emoticons":1,"filestorage__core_Profile":1,"filestorage__core_Theme":1,"filestorage__downloads_Files":1,"filestorage__downloads_Screenshots":1,"filestorage__calendar_Events":1,"filestorage__forums_Icons":1,"filestorage__gallery_Images":1,"filestorage__blog_Blogs":1,"filestorage__blog_Entries":1,"filestorage__core_Clubs":1,"filestorage__core_Reaction":1,"filestorage__core_Login":1,"filestorage__core_Imageproxycache":1,"filestorage__core_ProfileField":1,"filestorage__core_Promote":1,"filestorage__core_ClubField":1,"filestorage__cms_Media":1,"filestorage__cms_Pages":1,"filestorage__cms_Records":1,"filestorage__bbt_Chart":1,"filestorage__links_linkField":1,"filestorage__links_Icon":1,"filestorage__links_Thumbnail":1,"filestorage__nexus_Ads":1,"filestorage__nexus_Support":1,"filestorage__nexus_PackageGroups":1,"filestorage__nexus_Products":1,"filestorage__nexus_Customer":1,"filestorage__nexus_PurchaseFields":1,"filestorage__nexus_ReferralBanners":1,"filestorage__featuredcontent_Image":1,"filestorage__nexus_Product":1,"filestorage__core_Icons":1,"filestorage__clubcats_FileStorage":1,"filestorage__chatbox_Nofifile":1,"filestorage__nbpollswalls_Cover":1,"filestorage__nbpollswalls_Icon":1,"filestorage__core_Feature":1,"filestorage__core_ReferralBanners":1,"filestorage__forums_Cards":1,"filestorage__badges_FileStorage":1}
No path.
I have replaced the path in core_file_storage with the valid path for the test server. But the error persists, and var_dump still prints the path for the live server out. Datastore folder is emptied.
