Okay, I got this message when I upgraded PHP to version 5.2. The cause was a few includes that linked to remote files. I couldn’t easily find the answer, so I solved it after doing a bit of research.
The solution is quite simple. Find your php.ini file and add the following line:
allow_url_include = On
This did not exist in my PHP.ini file, but if it does exists in yours, just change it to “On”. If you have a similar message but it pertains to fopen, the solution is basically the same.
Add this line to the PHP.ini
allow_url_fopen = On
The same rules apply: add it if isn’t there or modify it if it isn’t.
Hopefully this post will save you some time. I personally love it when I can quickly find the answer using a search engine, so maybe this will help you out.
