Sorry about the issue guys. We just pushed out a fix in version 1.4.1.
The error happened due to a code conflict with older PHP versions.
Please update and let us know if you run into any issues (hopefully it will be smooth sailing from here).
Thanks for your patience
Update has worked. will revise my review stars to 5.
I’m also having this issue! I’ve gotten this error and have to delete the plugin in order to fix the site.
