I've attached the info.php file. I used ubuntu 8.04.1 and I leave out the steps of ISPConfig because I will has only 2 websites inside server. I have a script in php running in my oder server and it has few requirements, I would like to know if anybody can reply the following questions: 1- I need to have ImageMagick, GD, Zlib, MCrypt, Expat library. Looking the software installed in step 11 and 17 of tutorial: zlib1g-dev php5-gd php5-mcrypt php5-imagick libexpat1 Do I need any other soft to cover the requirements? 2- I need GzInflate enabled. How can I know if this is enable? or if it is not enable, how can I put enable? 3- I have Google Checkout and it require the following: Php compiled with cURL cURL compiled with SSL support. cURL enabled, not just compiled. Php compiled with imap support. How can I know if all are done or how can I do it if I haven't? 4- And finally I need: SimpleXML extension installed and loaded. How can I install it or know if I already have it? Thanks in advance!
