Our mailchimp/magento plugin is either broken or down. Its causing our subscribers on mail chimp to unsubscribe. We had this problem before and it was the plugin that had problems.
We can give you access to our admin portal so you can work on the changes.
Please advise how many hours you need to fix this issue and your best price. Please also specify if you are a magento certified progrmmer? This will help in us choosing the right candidate.
Note; If you require access to the server via ftp then we would need to ask you download our test server to your local machine, make changes on your local machine and then push them to the test server using GIT via bit bucket. We have a bitbucket account. Its unlikely you will need access to the files anyway but please note this is our procedure if you do.
