• I have been getting this Precondition error while using WordPress. All suggestions offered have not work.

    Now I decided to try the following:

    1. Export the current wordpress mysql database. I exported all tables in sql format with no compression.

    2. created a new WordPress directory with a different name then the old one, created a new database and installed WordPress again in this new directory.

    3. Went into the new mysql database to import the exported sql file from the old database. Got an error.

    I’m no sql expert so I was wondering if anyone else has tried this and what are the pitfalls I need to look out for. Can this be done? If so, how?

    thanks
    Steve

  • “Got an error.”

    What exactly ?

    sorry, I should of mention that. also, maybe I should mention I’m using phpmyadmin to try to do this. When I go to the new database I click on the SQL tab and use the function to browse and locate the sql file. Here is the error I get (I copied and pasted it).

    Error
    SQL query:

    — phpMyAdmin SQL Dump

    “created a new database and installed WordPress again in this new directory.”

    Create database.
    Do NOT install WP, just import the db.
    To cure:
    – DROP the tables in the db
    – Import your sql ??

    While exporting you may have omitted the following options in structure:

    Add DROP TABLE
    Add IF NOT EXIST

    When you install wordpress it creates empty tables.
    You should “drop” them and insert your old data instead.

    Podz…not sure I get your comment.

    I have to intall a fresh copy of WordPress to eliminate the error i keep getting.

    Doesn’t dropping a database delete it. That seems dangerous. What happens if I don’t get it to import properly in the new database…gulp!

    I don’t see any import function in phpmyadmin. I see an export tab, but nothing about importing a database. The only thing I found close is under the SQL tab which has a function to browse for a sql file which I used to browse for the sql file I exported.

    Help please….sorry guys, my knowledge of sql is limited.

    On the right there will be a guide that covers what you need.
    Your sql file. Copy it. Keep the original. Work off the copy.

    Thanks podz for your efforts. I read you info on your site (very nice site by the way), but nothing seems to work. This all started with that darn Precondition Failure errro and after two weeks of trying to get it resolved I’m mentally exhausted.

    I hate the thought, but maybe I need to look for another blog program. I would hate the thought of reinstalling WordPress again, copying it over to new installation and down the road this same error popus up again. I know, no guarantees, but with my little knowledge, not sure what else to do.

    thanks for your efforts. it was appreciated.

    I can import the db for you and get that working. As for the error – that could be anywhere from your ISP’s cache and further. It is not always your browser. Has your ISP got a suport number / forums ?

    Wow Podz…you are fantastic…hope this pays off for someone else besides me.

    Well, I didn’t give up. Did more searching and this time I got the exported database to execute in the new database without error. Man, I thought great.

    Then I typed the new directory in the browser and it came up a blank page….hmmmmmmm.

    No errors, just a blank page instead of the WordPress home page/index page. I’m sure the right tweaking would fix it. Any idea what it is?

    thanks again
    steve

    p.s. I battled my host about the Precondition failure error….they don’t seem to care nor will they help.

    Blank page – try changing the theme ?

    Yep, sometimes happens if you forget to set the theme back to default before exporting the database….

    Yep it was a theme thing, but I also got the same Precondition failed error. Uncanny! I can’t get rid of it and WordPress the only place it exist.

    Well guys, your help has been appreciated, but for now I’m going to put this to bed or I’ll be at it until Christmas.

    However, I learn a lot along the way. Thank you for that.

    Steve
