Just got this from my host:
"Thank you for writing in.
We have disabled allow_url_fopen php configuration on the server due to
its hacking vulnerabilities ,very few applications require it, and by
disabling it we will prevent exploitation of PHP remote include
vulnerabilities. Applications that do require it can be modified to use
cURL instead. Use a function in curl instead of file_get_contents()"
which will perform the same task for you. Please contact your developer
and modify the code in your files."
OK - How do I do this??
