I updated the d/b and changed the settings in my wp-config file but when I try to update to 3.2 I still get the error message telling me that I need the 5.0 version. I'm absolutely certain it is hitting the right d/b. Is there something else I should be doing? Unfortunately, I’m having as good a luck as you all.

Right now, I'm more concerned about performance than the characters. But I'll give it a whirl and see if it helps. Also, for another site on 4.0, I exported from within WordPress and then imported into a new database within a new WordPress installation. That worked well, but I did lose some of the databases (not related specifically to WordPress). Jon: Glad to hear it and thanks for the offer.

Let me know if you have any questions and I'd be happy to help out. Best, Jon Maria,

I've noticed a slowdown in my database's response time, especially for administrative tasks. But I didn't do the export/import. I did a backup and restore, using my host's MySQL tools. That might be my problem. Perhaps I should have exported from within WordPress. I have another site to update -- it's still running a VERY old version of WordPress -- and I'll experiment a bit with that. If I have success, I'll redo my main site and (of course) blog or comment about it here. Thanks again for the link. Jon: I’ll definitely review the article.

If I'm reading this correctly, if you have to import the database using an ASCII character set, and then use the search and replace plugin on his site to replace the "??" characters. The kicker seems to be that by importing with the ASCII character set, "??" is created instead of the question mark inside a black box (which is what I'm getting) and search and replace can replace those characters. This is probably one of many solutions. I'm not at my home computer at the moment with my database backup so I can't try this, but will do so when I return (unless I find a better solution).

I'm told that (1) I may have exported the database incorrectly (although I used Wordpress's built-in backup tool, so I'm not sure what I could've done differently); and (2) the weird characters are showing up at space characters that didn't get translated properly, and that there should be a query to run to clean all of those up. Unfortunately, I haven't figure out what that query is yet! Merry Christmas! Okay, a couple things to add on the weird junk characters appearing.

A couple of additional tips: 1) I needed php.ini file in each of my blogs to increase the memory allocation for PHP up to 64M. I used this code in the php.ini file with success: ;; set memory limit for cache.php upload_max_filesize:20 M max_execution_time:300 memory_limit:64 M post_max_size:8 M SMTP:localhost 2) For updating from mysql v4 to v5, I ran SQL exports to a file of the v4 database, but then hit a wall in the "import file" option. It only allowed 2mb file so I had to break up my SQL export into 6 partial files. Pretty straight forward though one has be careful on breaking the file. Also remember to remove the "create database" line a the top of the file since all one wants is to create and populate tables. Overall, fairly straight forward once I got my plan and was careful on the steps. Remember to also keep your v4 databases and old wp_config.php file safe in case you need to return to it.

That's one of the side effects of upgrading to 5.0, I think. Jay: Have you also had weird characters appear alongside special characters in your text?

If I get time this week, I'll hunt around a bit. I distinctly remember doing a find/replace in my database a long time ago, but can't remember HOW I did it. Maybe I'll find something online to refresh my memory. Jon: Good luck. If I get time this week, I’ll hunt around a bit.

Unfortunately, I too am no guru when it comes to MySQL. It looks like there's a long list of incompatibilities between MySQL 4 and MySQL 5: http://dev.mysql.com/doc/refman/5.0/en/upgrading-from-previous-series.html. This issue is probably buried there somewhere. I'll keep my eyes and ears pealed for a solution. Thanks for the response. Unfortunately, I too am no guru when it comes to MySQL.

It's mostly weird characters just before special characters such as ° and ¢. Apparently, MySQL 4 handled special characters differently than MySQL 5 does. I'm sure the problem could be fixed by querying the database with some sort of find and replace command. I've done this in the past for simpler chores. If you know how to do queries try that. If you don't know how, you could research it and learn -- but not from me; I don't know enough about it to instruct. My solution is to simply reupload all the posts. I use an offline editing tool which was not affected and have all 2,000 of my posts stored within it. Of course, this doesn't solve the problem if it appears in comments. Whatever you do to resolve it, I'd appreciate a quick comment here to let me know. In the meantime, if I find a foolproof query solution and it works for me, I'll likely blog about it here. I'm sure we're not the only two WordPress users dealing with this right now. Jon: Unfortunately, I’m seeing the same thing.
