Critical error

Hello

I have a page on my blog with about 30 or so blogs which are collected by the aggregator. They work fine on the page but after the latest update they can no longer be recognised by a 3rd party email feeder like blogtrotrr (whereas before it did). I’ve tried to set up a custom url for the feed but when I try and open it says:

<![CDATA[
<p> <b>WP RSS Aggregator</b> has encountered a critical error. The safest course of action is to deactivate the plugin and any of its add-ons on this site using the button below. Once you’ve done that, you may reactivate them and start using the plugins again. If the problem persists, please copy the below error and send it to our support team with an explanation of when and how it happened. </p> <div style="background-color: rgba(0,0,0,.07); padding: 5px;"> <details> <summary style="cursor: pointer;"> Click to show error details </summary> <div style="padding-top: 10px; overflow-x: scroll;"> Error Message: <br/>

As per the error message suggestions, I’ve tried deactivating and deleting the plug-in a few times but it still comes up with this error. Any help is greatly appreciated.
