After logging in to administration backend of Joomla a blank or white page appears. Viewing the source, the following is displayed: <b>Fatal error</b>: Class 'jmModel' not found in <b>/.../public_html/administrator/components/com_joomailermailchimpintegration/models/campaigns.php</b> on line <b>19</b><br />

How do I clear this error so I can gain access?

Which joomlamailer version and Joomla version are you using?

To fix this problem for now please edit the file:

administrator/components/com_joomailermailchimpintegration/models/campaigns.php

Add this code at line 18 (above "class ...")
Code:
require_once('jmModel.php');

Once you have regained access please install the latest joomlaversion again on top. Possibly it did not install properly.

Pete

pete,

I am closer but still have the white page. I am the hosting admin of the site not the site admin so I cannot provide joomla or joomlamailer versions but believe joomla is 3.x

Page source error is now:

Fatal error</b>: Class 'joomailermailchimpintegrationsModelCampaigns' not found in <b>/.../administrator/modules/mod_mailchimpstats/mod_mailchimpstats.php</b> on line <b>36</b><br />

Looks like your joomlamailer version very outdated (below 2.0). You can gain access to the backend again by disabling the mailchimpstats module directly in the database. you find it with this query:

SELECT * FROM #__extensions WHERE `element` LIKE 'mod_mailchimpstats';

Set enabled to zero.

Then install the latest version and everything should be fine.

Regards,
Peter
