@stefano79roma Once you have installed the current version if you have problems you can open a bug report. It’s unlikely that you’ll have support on such an old version of the plugin.

the problem is sure not about the server

What makes you so sure? So, it’s not true that nothing has changed in the last 24 hours, if the message comes from your software installation as you say.
That message means that maximum time limit on server (not necessarily a web server) isn’t enough for the execution of the script. So, if on a local server it works, and it works also changing browser/pc/network connection, open a ticket with your web service provider (Aruba?) and ask for the error log.

and ALL singlepics shortcodes are gone

@jesusgpastor Do you mean that single pic shortcodes have disappeared?
Can’t you see them in post editor?
My idea is that you still have shortcodes in posts editor, but maybe you can’t see single pics because you excluded them from “manage gallery”, in order not to repeat them in the gallery.
Is this the case?

@cherrychase Open custom menu and delete that HOME tab.
Now click on the arrow near “Help” at the right top side, it opens a dropdown menu with some checkboxes, check “Link”, close.
At the left side, now you’ll see a widget called Link, write in URL the link you want to open to, write HOME in the text and then click “add to menu”, et voilà.

P.S.: Disable skysa weather plugin, it gives an error.

@batharoy, cherrychase doesn’t want a static home page.

@jon_highland using a WordPress version this old is like keeping an open door for hackers

And I answered you that you can set dimensions in Gallery settings before uploading new images. Isn’t what you asked for?
Have you tried and doesn’t work?

When you say “Post to Page” do you mean Attach to Post?
As for the 3 columns add in Nextgen custom CSS area
.ngg-gallery-thumbnail img {margin: 20px 50px;}
or
.ngg-gallery-thumbnail img {margin: 20px 50px !important;}
With regard to the issue, it seems a conflict between the two plugins. You have to test activating default WP theme and deactivating other plugins.
BTW, is there a particular reason for which you can’t use the first method?

If just before the changes it was working and now it’s not, the problem is in relation to those changes. If you have added some code found on the net without really knowing how and what it does and if you have modified .htaccess, then you may have done more harm than good. The solution is to remove the “improvements” and return to the previous state of things.
At the moment if you activate default WP theme and deactivate all other plugins, you can have further evidence on what it’s going on.
