First of all this is a very nice tool. I bought it some time ago, but now I have this issue:
If you browse the products the first three pages of the listing (180 products) work fine. If you skip to page 4 nothing is shown (except the violet background). So unfortunately I only can edit 180 of my 300 products. The pagination seems to have some problems either sometimes it displays funny things like page 5 of 4 (with no content of course).
Is this a known bug which has been solved inbetween?
My version is perhaps not the newest (2.0.24), but I can't upgrade. My order number is accepted, but upgrade doesn't work...
if you meet the requirements for max execution time and memory on your webserver and it is still the same problem I guess you are using PHP 7. In my cases it is reproducable: Everything is ok with PHP 5, if you switch to PHP 7 the plugin doesn't work correct anymore.
