The site only loads with the error and no content. I can’t even get into WordPress admin page. * Fatal error: Class ‘NS_Widget_MailChimp’ not found in /home/sites/hikmah.co.uk/ public_html/site/wp-includes/widgets.php on line 324 * Appreciate the help, * Sid.

If you could also provide us with a link to your site. I’ll be happy to have a peek! * Thread Starter [sid17](https://wordpress.org/support/users/sid17/) * (@sid17) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059196) * Hi mc_nate, * Thanks for getting back to me. I’m using WordPress 3.1.1 and version 0.8 of the MailChimp widget. * The site URL is: [http://www.hikmah.co.uk/site/](http://www.hikmah.co.uk/site/) * [mc_nate](https://wordpress.org/support/users/mc_nate/) * (@mc_nate) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059217) * Hey again, Sid. * I’m not sure that 0.8 was actually a version that was released by MailChimp. You can find all of our previous versions here: * [http://wordpress.org/extend/plugins/mailchimp/](http://wordpress.org/extend/plugins/mailchimp/) * [mc_nate](https://wordpress.org/support/users/mc_nate/) * (@mc_nate) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059218) * You might want to try using version 1.2.4 as it’s the most up-to-date version of the plugin that we have. * [JillW](https://wordpress.org/support/users/jillw/) * (@jillw) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059238) * I have got exactly the same error. Fatal error: Class ‘NS_Widget_MailChimp’ not found in /home3/holwellf/public_html/johnnymartin/wp-includes/widgets.php on line 324 * Any ideas? I can’t access the admin panel or anything! * Thanks * Jill * Thread Starter [sid17](https://wordpress.org/support/users/sid17/) * (@sid17) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059239) * Hi Jill, * I couldn’t fix it… * Sid. * [JillW](https://wordpress.org/support/users/jillw/) * (@jillw) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059240) * Hi Sid, Thanks for the reply. Not exactly what I wanted to hear!! What did you do? Scrap your whole site? * Jill * Thread Starter [sid17](https://wordpress.org/support/users/sid17/) * (@sid17) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059241) * Yep, I started from scratch and used another plugin for mailing instead. * I’ve kept the copy of the wordpress install that is still displaying the error in the hope of fixing it one day. * [JillW](https://wordpress.org/support/users/jillw/) * (@jillw) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059242) * That’s all very depressing news. * Fortunately not a massive site. Time for tea and chocolate I think. Cheers Jill * [JillW](https://wordpress.org/support/users/jillw/) * (@jillw) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059243) * Sid I thought I would let you know I resolved it by deleting the mailchimp plug in in the wordpress folder on the server and it has reverted back to the normally functioning site – phew. * Not a long term fix I know but it has got me out of the mire for now. * Ah the power of chocolate! * Cheers Jill * Thread Starter [sid17](https://wordpress.org/support/users/sid17/) * (@sid17) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059245) * Nice one Jill, thanks for letting me know. * I’ve normally have a packet of custard creams on the side to help me get through. Must try chocolate in future. 😛 Sid. * [mc_nate](https://wordpress.org/support/users/mc_nate/) * (@mc_nate) * [15 years ago](https://wordpress.org/support/topic/mail-chimp-causing-fatal-error/#post-2059248) * Hey Sid and Jill! * Just wanted to follow back up with you guys. I was unable to replicate the same issues on my end of things. I upgraded to WordPress 3.1.2 and have the MailChimp 1.2.4 widget running in site. Here’s a screenshot real quick: * [http://screencast.com/t/WMpptQtr](http://screencast.com/t/WMpptQtr) * Are there any special themes installed? * If not, it sounds like it could be a conflict with another plugin that’s being used… * Hmm. Let me know any additional details and I’ll give it a shot! * Cheers.
