Importing database from PHPmyAdmin export

    Today I took a database backup (via PHPmyAdmin export) prior to making some changes to an old website, built in 2011. The site was using WP 3.4, with a 2010 child theme. After doing the database export I also used FTP to copy the entire wordpress directory to my local HDD.

    Then I went into the dashboard, and before making my own changes I decided to upgrade to 3.6. After the upgrade, many images seemed to be broken, and the site loaded slowly. I decided to just restore the backup and continue with WP3.4. Using directions here, I used PHPmyAdmin to start the import of my exported file, and quickly saw this error message:
    ——————–
    SQL query:
    —
    — Database: pool1965_wrdp1
    —
    CREATE DATABASE pool1965_wrdp1 DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;

    MySQL said: Documentation
    #1007 – Can’t create database ‘pool1965_wrdp1’; database exists

    ——————-

    I didn’t do any other steps during the original backup, and suspect that I may not have my pages in the backup (there are no posts). So I’m guessing I can’t simply drop the existing db and import the backup.

    I’m reasonably comfortable with PHPmyAdmin but I’ve never tried to restore a db before. I could use some advice on how to proceed.

    Thanks in advance.

    Try:
    – switching to the default theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

    – resetting the plugins folder by FTP or phpMyAdmin.

    – re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

    – running the upgrade manually via wp-admin/upgrade.php

    Thank you for the quick response!

    It turns out that this was a caching problem in Chrome. I cleared cache, closed all Chrome windows, and quit Chrome. After a couple minutes I tried again and most of the problems were solved. Site still loads images more slowly than it did using WP 3.4, but not as dramatically slow now.

    Now I don’t feel the need to restore the backup.

    Have you tried:

    – deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

    – switching to the default theme to rule out any theme-specific problems.

    – resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

    It apparently wasn’t just a caching issue, as its happening again (even on a different computer). Page loads with most images broken. Reload the page and some images appear. Refresh again and different images appear. Occasionally all images will appear. Sometimes I see “Oops! Google Chrome could not connect to (mysite.com)”

    I think the db is corrupted, so I’ll revert to your first response and see if that will fix it.

    After all this…what I’d REALLY prefer is to simply go back to WP 3.4 using my db export file. It looks like your recommendations are to salvage the 3.6 upgrade. Do you have additional recommendations that would help me get back to where I started?

    edit: I did try to deactivate all plugins, then reactivate one at a time. This had no effect on the sites inability to load all images. Also tried resetting to default 2010 theme: still had many missing images. There were no missing images before I upgraded to WP3.6.

    Do you have a pre-upgrade database backup?

    Yes. As I said in the initial post, I used PHPMyAdmin to do an sql export. Then I also used FTP to download the entire wordpress directory. Then when things went wrong, I used the directions at http://codex.wordpress.org/Restoring_Your_Database_From_Backup
    to start the import of my exported file, and quickly saw this error message:
    ——————–
    SQL query:
    —
    — Database: pool1965_wrdp1
    —
    CREATE DATABASE pool1965_wrdp1 DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;

    MySQL said: Documentation
    #1007 – Can’t create database ‘pool1965_wrdp1’; database exists

    I’ve since asked the web hosting company to restore their backup. They’ve done so, but I’m still having the same problems. It’s not a caching issue, as this occurs on different computers and in Incognito windows.

    What could cause the site to fail to display images? Even after restoring a server backup from a time weeks prior to the 3.6 upgrade?
