Gallery with Joomla 1.5

My Photogallery on Joomla 1.5 stopped working while the same site gallery works fine with other hosting companies. I get the following message when trying to enter my gallery:
Fatal error: Call to undefined function curl_init() in /users/detsad31/www/components/com_picasa2gallery/libraries/helpers/Gdata.php on line 46
I tried a different gallery (Rokin Gallery). It was successfullry installed but it doesn’t function either. Are there any funcionality limitations on server? Is there any way to make gallery extensions work properly?
Thank you.


well, cURL is available, but requires bplaced pro (see - nevertheless Joomla 1.5 is seriously deprecated and must not be used any more. Please evaluate an upgrade to the 3 series or at least 2.5, 1.5 has lots of unfixed/unpatched security issues, pages relying on that software are being hijacked all the time.
