1. Old wordpress version
2. Using old theme
3. Using old plugins
Those 3 factors combined together and lead to ‘unstable’ self hosting wordpress.
Newest wordpress offer automatic upgrade for the version but you must do the rest (upgrading theme and plugins).
Those issue corrected by Softaculous. If you want to install new blog I suggest you to use these settings :
1. Database name : enter your blog name as component. ex, if your blog is about flower then fill flowerdb or mydbflower. It will save you from headache in the future.
2. Table prefix : enter shortname of your blog, ex: flo_ . Don’t use wp_ .
3. Use strong password. You can click ‘key’ icon next to admin password input.
4. Use advanced option. Make sure to check 3 options (auto upgrade, auto upgrade wordpress plugin and auto upgrade wordpress theme).
Using that setting will give you ‘health’ wordpress that give you long run blogging platform without worrying about late update action.
How about existing blog?
I’ll create separate post to explain it in step by step mode.
