I purchased the eBook plugin years ago. Now the version (5.8001) I have is being flagged by Wordfence as having a critical security problem and is not tested for the version of Wordpress I have. However, there is no option to update to a newer version just an option to "Upgrade" (i.e. to purchase a PRO version). Is that correct? I thought when I purchased the original plugin (I admit it was a long time ago) it would be updated forever. Is the only option now to buy the newer Pro version? If so I may be looking for an alternative.
