Hi.
I don’t have the same issue when using this plugin.
You should first fix the errors given by your child theme and see if those adjustments fix the issue.
OTW, has been around for awhile and sells premium plugins, so support for their free plugins is probably limited or comes available only as they are become available to provide it.
I took a look at the plugin and it seems (at the least) a file has been left out, but they are still referencing it.
In otw_blog_manager_light.php on line 873, try commenting that line out so it looks like…
//include( 'social-shares.php' ); because this file doesn’t exist, which is why you are getting the class not found error.
I’m not sure how commeintgin that out will affect eh display of the plugin though. But after which you should comment out the action called to that function.
So starting at line 129, you can make it to look like…
// Ajax FE Social Share
//add_action( 'wp_ajax_social_share', array($this, 'otw_bm_social_share') );
//add_action( 'wp_ajax_nopriv_social_share', array($this, 'otw_bm_social_share') );
There would still be a few optimization to be done since the social-shares.php file is missing. Ultimately the best solution is for that file to be included, which might of been left out by mistake, or the plugin could just use some adjustments.
At least, that is what I see so far.
