triple-5

Thanks! That did the trick!! According to the Simplemap support site, this is a known bug and a fix has an ETA of 4-15-2012.

You can add logos by editing the logo-slider.php and options.php files in the plug-in folder. You can add as many logo’s as you need.
Be aware though, two places need to be edited in the options.php file to have things work properly.

I was able to finally able to resolve the issue, but it took a bit of work. Involves working directly with the database in mPHPadmin, not for the weak of heart!
With that said, her goes..
Back-up your database! This is important!

1) in myPHPadmin (or whatever database tool you use) export the wp_ngg_xxx tables (3 or 4)
2) Deactivate and delete the plugin.
3) activate the plugin
4) import the exported gallery data

That did the trick for me, but no guarantees.

I am having this same problem on only one of many websites we have designed.
Everything works fine when using the short code, but when we use the widget in the page or post editor, it can’t seem to find the galleries. Dial just sits and spins. On this one site, i have almost 50 galleries. is this a potential problem? The others that are working correctly, have less than 10. there is one site where the widget is working correctly, but only lists about the 50 most recent galleries (400 total). I have reinstalled the plug-in on the site in question, nothing seems to work..

What gives? Could use some ideas..
