Hi....i am creating a dolphin community but when i click on groups,files and videos i get warning messages which i am mentioning below.kindly help me...its very urgent..Thanks in advance

Warning: fopen(/home/entrance/public_html/dolphin/cache/sys_objects_actions.inc) [function.fopen]: failed to open stream: Permission denied in /home/entrance/public_html/dolphin/templates/base/scripts/BxBaseFunctions.php on line 416


Hosting support team is saying error is because they have disabled fopen(because of security reasons) and to use cURL instead. I am a novice and don't know any coding.
What should i do ?

You need to ask them to enable that settings. Also, you can choose www.happy-hosting.com for your dolphin.
