Apologies if the SCORM cURL implementation is covered by the following:
I am getting an IE Error 404 (and Firefox) when I try and open SCOEs with non-local resources (i.e. stored on a supplier's server). They were previously working and local SCOEs (with resources stored on our server) still work, but like many ISP's, they have recently disabled the allow_url_fopen function, as this is proving to be a major issue for my site as I have a large number of 'Midleaders' SCORMS (potentially 200) which I can no longer access, my ISP recommending that cURL is used as an alternative. They will not re-enable the function. We have around 800 users which means my site is in maintenance mode with a around 800 users unable to access their learning - so things are pretty desperate! I am on a semi-maintained shared server hosting plan with a UK company called Evo Hosting, so cannot make Apache configuration changes myself, although I have CPanel access and maintain our installation.
I'd be happy to provide a test login if required, and use our site to test implementation.
