Frequent Disconnects btwn moodle and joomla

Nice work on joomdle app,

am running joomla 1.5, joomdle 0.6, moodle 2.0 and i keep getting inconsistency in pulling courses from moodle to appear in joomla.
(e.g) upon login (mod_joomdle_courses, mod_joomdle_my_courses & joomdle shop)the courses dont appear but after refreshing the page they display and after another refresh they disappear not in any particular order.

what could be causing the disconnect.

Hi,
they are all green apart from
Joomdle Web Services which is green and turns red after refreshing as well and back to red after another refresh.

i did the installation on wamp and it works well but on my host it gives me the mentioned errors

my bad,
forgot to mention
PHP reporting error is enabled,
"E_DEPRECATED errors are enabled in your PHP configuration"

i contacted my host to disable it, then will respond the out come after that.
many thanks

edited the php.ini host file and .htaccess and managed to disable the E_DEPRECATED error and the connection become stable.

then when i click on a course enroll button, i receive this errors: cant figure what it means

1."XML-RPC Error (0): Coding error detected, it must be fixed by a programmer: invalid enroll instance!"

2. when opening moodle link using wrapper it appears briefly on joomla with course details and then vanishes. when i try a new window it takes me the moodle subdomain.

any take on this
