yes, we know some inconsistent with NextGEN Gallery.
we updated our plugin to 1.4.3 last week because of there was no upload-button at our plugin anymore. We didnt solved this problems yet for all cases, at least one of our customers still doesnt have that upload button. Maybe its another plugin which causes that error.
But you mean that our plugin interfere NextGENGallery. Is that error really disappearing if you disable the 1000grad-ePaper plugin at your installation?
YES,that error disappearing after deactivating the 1000grad-ePaper plugin.
where is that photo gallery problem in detail, is it in the admin-area? we are not familiar with that plugin.
we checked that twice.. the nextgen-gallery may not be the problem. at our installations thats running fine, both plugins together.
But, you have 57 js files included, and there are many js-errors when opening your webpage. Please have a look f.i. at your google plus api and some inline-css errors. SyntaxError: illegal character..
