That requires changes to your stylesheet, and would be much easier for people to answer if they could take a look at the site. ??

The page is created by WordPress if the file is “linked to page” (as described here), and the comment may just have been a spam comment.

You will probably get rid of it if you edit the post and set it to “linked to file” instead.

I believe the Filosofo Old-Style Upload plugin does that (among other things): https://www.ilfilosofo.com/blog/old-style-upload/

No need to go into the WordPress files, the errors come from faulty markup in the actual posts. Just edit the posts, using the html editor in the write panel to remove the tags.

These problems usually happen when you try to insert code into posts from the visual rich editor and it tries to correct things.

No, there’s a few more things to do, most importantly moving the databases.

Database specific information: https://www.tamba2.org.uk/wordpress/backup/ (backup)

Read those, and if some things seem complicated just return here with any further questions. ??

Did you notice that the problem only occurs on the index and the first post, and not when you look at other posts? I took a look at the page source… and the most likely cause would be that you have a </div> at the end of that post. Get rid of that by editing the html of the post, and it should unbreak the whole page. ??

Edit: The bottom post seems fishy as well, but all the other first page posts had sidebars in the right place, including the one with the wide image.

Try adding padding to this definition:
p img {
padding: 0;
max-width: 100%;
}

There seems to be a lot of redundant <div align="left"></div> stuff in your most recent post. Cleaning up the html source of that post should fix the problems.

You have to change the URI in Options/General before moving. Documentation on moving WordPress here: https://codex.www.ads-software.com/Moving_WordPress

Just one more thought before I say I’m sorry that I couldn’t help: did you run a localized version, and did you make sure to upload the language file after upgrade?

Not sure how large the effect of a missing language file would be, but maybe it could explain the dashboard problems.

Maybe should wait for the real experts on this, but here’s what I can think of:

If you have a backup, get the old theme files from there. Also, remove all non-standard plugins from the plugins folder, see if you can log in and then upload the plugins and activate them one by one to see where the problems start.

Did you have any category related plugins or theme modifications before you upgraded? Could be that something got overwritten during the upgrade.

A quick guess: Firefox renders #maintable at 100% of page width, and not the width of the div that contains it. Or maybe because the first td has a set width and not the other. Or maybe a combination of both… it’s in that area I’d look, anyway.

I’d try to get rid of those tables completely…

bdsays: you can update directly to 2.0.4. As far as I know, the upgrade works with all version from 1.5.x and up (in case someone else wonders). ??

WordPressMU is intended as a solution to host blog sites like wordpress.com – to run your own blogging “community”, so to speak. You would still have to manage eight individual blogs, and due to the scale it is less flexible than the regular version.
