Need some to take over the care and feeding of Joomla site

[volution]

Currently the problem is that suddenly won't add products to cart

After that is fixed, I want to connect the client with someone who really knows joomla
She needs a slider and other issues that are beyond my skill set

joomla!  2.5.19.
virtumart   2.0.14
Php 5.3.3

It just suddenly stopped working.  The only major operations have been installing security certificates.

I updated joomla to see if that helped. It didn't

Just a few hints:
VirtueMart 2.0.14 is afaik not 100% compatible with Joomla 2.5.19, due to changes in the latest versions of Joomla. So you should update VirtueMart (try with a seperate backup first, because 2.0.14 is pretty old) to 2.0.26d or higher.
Looks like you have enabled SSL on your entire site. Did you try already if the cart works again if you set 'Force SSL' in Joomla 'Global Configuration > Server tab' to 'none'? VM has a configuration option 'Enable SSL for sensitive areas (recommended)', which is sufficient.

how did you make out?

really, make sure you do the update to.26d on a dev copy,  not on live, or you will just make things worse

if you still need help, we can work something out, we do upgrades all the time
