Update Problem – Trying to migrate $$$ blog t WP…

-Are you using Windows server?
-Have you contacted your hosts about this?

Yes and I contacted my host — and I did mention that I’m unable to perform auto updates from the WP dashboard… no concrete response. It’s the weekend…

I ended up totally removing what was uploaded Friday evening (3.5.1) which was working fine until yesterday morning. I started fresh and uploaded 3.5.2, again following all of the detailed instructions. HOWEVER, for some reason, I get this error message when I try to login:

PHP Fatal error: Call to undefined function nocache_headers() in E:\USERS\HappyHour1\www\HHOABLOG\wp-admin\admin.php on line 32

WHY it’s referencing an “E” drive, I have no idea. I have backup drives but none have been accessed for any WP stuff – yet.

I opened the above admin.php folder in Notepad++ at line 32: nocache_headers();

Is there something that should be inserted inside the parentheses? I suspect so?

While I’m learning every day, I am by no means a code guru — just a layperson… ??

If someone knows, please advise. Then I can insert what needs to be inserted, save, and upload to server again.

Thanks so much!

try:

-deactivating ALL plugins (yes, all) temporarily to see if this resolves the problem. If this works, re-activate them individually (one-by-one) to find the problematic plugin(s). If you can’t get into your admin dashboard, try deactivating via FTP or SFTP or whatever file management application your host provides. If applicible, also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to mu-plugins-old.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems (because the hooks remain unless plugins completely removed or some plugins stick around in cached files. So by renaming the folder, you break them and force them inactive).
– To rule out any theme-specific issue, try switching to the unedited default Twenty Twelve theme for a moment using the WP dashboard. If you don’t have access to your admin area, you can switch to the default theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using via FTP or SFTP or whatever file management application your host provides.

Thanks very much for your feedback, Tara. I haven’t settled on a theme yet or plugins – I only got to play around in the DB and tour the program a little. After I posted this help request, I researched further, and evidently this issue has occurred before in WP after installation/updating functions – at least from what I Googled. I’m trying to research so I can fix it myself, but I’m not sure — it appears this error can occur for multiple reasons?

Can I still have a plugin or theme issue even though I deleted everything from 3.5.1 from both places (meaning host and my computer files) and uploaded via FileZilla the new, complete 3.5.2 version?

Could the problem be that since I was in the dashboard and WP program yesterday, even though I didn’t save any work per se, that the templates and plugins I looked at (with the default Twenty Twelve being one of them) as I was “touring” WP with guidelines in hand, could have caused this problem? Maybe that old info is not yet cleared out?

Should I first compare each file size with what’s on my computer vs. what is uploaded to my host? I think the total # of bytes is about 12,070 (have to verify the last 3 digits)?

Before I deactivate the plugins, I would like to confirm, if possible if my specific issue can be corrected via inserting code within the parentheses as I asked above? I have no problem in admitting I have no idea! LOL

Or possibly, should I again uninstall the whole program on host server and computer and start over. I’m just not sure. I’m trying to research and resolve this, but I don’t think I understand enough just yet to discern the problem — only from what I’ve read today. In one case, it appeared to a browser-related issue; another a server issue…

Thanks again for your suggestions. Before I move forward with resetting the plugins folder, I’m hopeful additional WP-knowledgeable like yourself, will chime in before I make too many changes.

I sincerely appreciate your suggestions. Because of this problem, it’s taking me away from updating the rest of the site (not in WP yet – I’m transitioning) — that said, the blog portion is critical.
