Well, I did not updated NextGen on my main site after reading all the mess in this forum and would prefer to use previous version because afetr testing new one in my other site, there is missing so useful things I do not see any reason to update at all.
BUT - after I updated WordPress, now the previous version of NG not working anymore properly: Can not edit, rotate ... nothing, just a unactive window, no clickable links....
And new NG has most annoying upload sytem: after I upload it is not tehre the link "Uploaded succesfylly, GO TO EDIT the gallery which I loved so much because NOW I must go through 7 pages of galelries, to find the gallery I just uploaded to, that is huge time waste, one by one going through pages and pages till can find the gallery what I was updated with new pics. - not possible to search gallery list only images...... worthless new version, I am very disappointed and NOW THE PREVIOUS VERSION IS NOT WORKING NEITHER with latest wordpress version :(
No link as these problems are not front end ( except that every time when uploading pictures, the new thumbnails need to be created again and again, very annoying).
