Can you log into your server with something like phpMyAdmin and verify that the database is still there?
Yeah, i was able to fix it, by reading all the threads and asking the server to make a small rollback..
They fix the database.
Nevertheless i lost all my media in my webpage… why did this happened?
Luckly i made a backup a week ago.
So, even when i have multiserver.. if i want to try a new template in a new site… i should install wordpress again and don’t mess with the multisite?
which is the best option here?
I made a new root mysite.com/root1/root2
and tried to install a new wordpress but its constantly redirecting me to the original wordpress instalation…
this might be because of the multisite…
so if i install a new template
is there anyway for this new template to not mess with my old database?
like if i import new tables, or stuff…
which is the best way to handle this
When WordPress Multisite is enabled, there is no need to install WordPress multiple times. You can have as many sites as you want under one installation with one database. You can add a new site from the Network Admin – Sites – Add New menu.
If you want a different theme on one of the sites, once you upload/install a new theme in the wp-content/themes folder, the theme needs to be either Network Enabled (from Network Admin – Themes) or Enabled on one of the sites in your Network (from Network Admin – Sites – Edit Site – Themes). Then, you can activate it on the site you want. Otherwise it will be hidden.
Hi Dcleek thanks for your answer!!
So I get this about multisite instalations.
Can you help me to solve this problem:
If i install a new theme on a new site, and import the settings from the demo and stuff, there will be changes to the database… thus, if i regret this theme, or i want to make some changes (I.E delete this site, etc) i will lose some tables at my database again, and its a big mess.
Is there anyway to solve this? like to use multisite with different databases for each site?
Maybe im not seeing something coz of my lack of expertise… is there any advice to issue this?
thank you
When you add content to a site, that information is stored in the database. If you change themes, the content stays no matter the theme. It only changes the look and how it is displayed. Some things that would change are your widget areas and menus. You’ll need to make sure you know what goes in which widget area and where the menus were displayed. Each theme handles widgets/menus differently.
If you delete the site, yes those tables will be removed.
Changing themes should not remove any database tables. However, your new theme may not have all of the same features.
Try activating a different theme on that same site. Then, if you don’t like it, you can switch back by activating the older theme.
It might be good to set up a testing environment locally for you to try out your themes before making them live.
To clarify one thing, theme options are normally saved in the wp_options table (or in the case of multisite wp_x_options where x is the site ID).
Those options are only deleted if and when a theme is uninstalled via the WP admin panel. Even then, not all themes delete their options.
The only ‘loss’ people tend to encounter with theme switching is widgets getting moved around.
