I am having 2 issues with your Plugin “Page-Link Plus”.
before you respond I have tried several themes and “Page-Link” says it won’t work in any of them. I get “X Pagination Function: Not Found”. I contacted several of the themes authors and got 2 replies both stating they DO have the “wp_link_pages” function*
Strangely even though this message is given, your free version is doing what it’s supposed to do (providing the single page option).
I would be fine with this except since it works I purchased the complete version. I downloaded it and tried installing. I get the message “The package could not be installed. No valid plugins were found. Plugin installation failed.”.
All Our themes use wp_link_pages function. Without this function, theme will not pass theme review process both in wordpress.org and ThemeForest.
You can check it at content-single.php, content-page.php in our themes.
Feel free to contact us if there is anything else we can help.
