Support » Installing WordPress » 2.3 > 2.5 Problems! PLEASE HELP ME!!

    OK, so I upgraded to 2.5, but I didn’t like the Dashboard and the inability to find my plug-ins. So, I decided to go ahead and move back to 2.3. I followed the backup instructions of putting my ‘www’ folder on my computer.

    I put the 2.3 www folder back onto my FTP, and now it isn’t working right.

    I can see my blog when I go to the site, but when I try to go to the wp-admin I get the following message:

    Warning: Cannot modify header information – headers already sent by (output started at /home/o*******/public_html/wp-config.php:47) in /home/o*******/public_html/wp-includes/pluggable.php on line 390

    (the o******* is protecting my login name, as I am not sure how safe it is to share it)

    Please tell me how I can fix this!

    Thank you in advance for your help.
    Jason

  • Can anyone help me?

    Am I posting this in the wrong section?

    If there is a more appropriate place on the forum for this post to go, please tell me.

    Thanks all,

    You are in the right section.

    When you applied the 2.5 version, did you run

    http://yourblogurl.com/wp-admin/upgrade.php

    Just putting the files for 2.3 back will not work unless you also restore the database back to it’s pre-2.5 state.

    If you have not backed up your database, I suggest you check your wp-config.php for any typos or errors, and try putting on a fresh copy of 2.5 without any plugins.

    Once you get 2.5 running then try putting it all back.

    Good luck,

    Jan,

    Thank you for the response!

    I don’t know if I backed up properly, but I basically copied the entire “www” folder off of my FTP when it was still 2.3. Then, I installed 2.5 and copied that “www” folder as well. They are in separate folders, so that they are not confused.

    When I didn’t like 2.5 I simply replaced the “www” on my FTP with the “www” that I pulled off when it was still 2.3.

    Does that make sense?

    Did I do something wrong? If so, can I fix it with what I have?

    Thanks again,
    Jason

    Hi Jason,
    I hate to be the bearer of bad news, but unless you actually made a back up of your database, you’re SOL. Although your files were in separate folders, if you used your previous database information for the new WP 2.5 install/upgrade, then your DB tables were upgraded to the 2.5 format and there’s no going back unless you have your WP 2.3 DB tables backed up.

    Based on what you said, you did not back up the database. 🙁 I don’t think anyone has made a tool that changes a DB back to an earlier version.

    As Jan said, check line 47 of wp-config.php for the problem.

    Yes: bear in mind that a WordPress blog is made of two elements:

    (a) The WordPress files, themes, etc.
    (b) The database

    Always back up both before you do anything radical.

    (Hi Teli!)

    That happened to me also. BACK UP BOTH!

    So, what does this mean for me?

    I go to my site and the page comes up fine. I just cannot get into my admin side.

    Are you all saying that there is no way to fix this? Even if I put the “www” folder back for 2.5?

    How do I get back to normal by starting over?

    I can reinstall 2.3.3, put my theme back onto it, and the cut and paste my 27 posts back over. They will all show a post date of today, but besides that everything would be back to new right?

    There are only 27 posts, and I probably only want to transfer over 20 or less. That wouldn’t take too long.

    Please let me know what I have to do to get my page back to normal, or if there is already a thread on how to do this — please direct me there.

    Also, please direct me to well written, detailed instructions for how to backup everything, so that this doesn’t happen again. I am a newbie to all of this, and have learned everything so far by reading around. I thought I have backed up properly per the instructions on WordPress codex, but apparently I missed something.

    Thank you all for your responses, and for helping me get back on my feet!

    Here are instructions for backing up your blog.

    If you do decide to ‘cut and paste’ your previous posts and re-insert them, you can change the dates on them back to the original ones easily in the ‘Post Timestamp’ section of the post editing page.

    OK, thanks wahgnube & kevinclapcott!

    Can someone tell me how to start a fresh database, so that I can add back my plugins, theme, and posts?

    Thanks!
    Jason

    > I go to my site and the page comes up fine. I just cannot get into my admin side.

    If you can see your blog and articles, then I wouldn’t start a new database. That means you’ll have to solve whatever’s causing the problem with the admin side, though … but at least you won’t need to start over.

    Or … you can just start over. But I’m not sure how that’s going to help, really, as you may just run into the same problem.

    Thanks DianeV. I was hoping that my site being there was a good sign!

    I downloaded Text Wrangler so that I could look at my php’s for problems, but I don’t know where to start.

    My message is:
    Warning: Cannot modify header information – headers already sent by (output started at /home/o*******/public_html/wp-config.php:47) in /home/o*******/public_html/wp-includes/pluggable.php on line 390

    Any ideas as to where I can start to look for the problem I am having with the admin side of things?

    edit: Also, are there any other places on this forum where they have a list of things to check based on your error message?

    Thanks everyone,
    Jason

    Yes, your blog being there is a great sign. I would just search for the actual error message:

    Cannot modify header information – headers already sent

    Thank you ALL!

    I searched the error message as DianeV suggest, and I found an FAQ that told me how to read the message & how it points me to an error on line 47 of wp-config.php — located in the public_html folder on my FTP!

    Sure enough it ends at line 45. Lines 46 & 47 were just blank space that was keeping me out.

    I am back into my admin, and everything is still there. StatPress even continued to monitor my traffic!

    Thank you so much everyone,
    Jason
