can’t add tags in 2.8

Disable plugins and see if the problem goes, that means all of them, not just the ones reported to cause problems..

It takes a few seconds to click disable for each plugin, then a few moments to open a new window/tab, test the page, then change focus back on the plugin page and re-enable if of no help…

Try another browser, try another PC, try anything that requires less then a minute of time..

If disabing plugins doesn’t help, get yourself a local installation running (can provide further info on this), install a fresh copy of WordPress (not on your site) on the local install and try to replicate the problem. If the problem doesn’t occur then you compare what differs from the new install and your problematic one (9/10 times it’s a plugin problem – which can usually be isolated without testing locally)…

I found my problem to be with WP Events Calendar plugin. I did an upgrade and then found out that the upgrade is still beta. I deleted the beta (6.6 beta) and reinstalled 6.5.2.1 and that solved the problem.

There’s a problem with wordpress 2.8 and simple tag plugin.
Original tag input in edit post is not hidden, so if you try to use it fail.

I fixed it with a small modification of a file:
/simple-tags/2.7/inc/simple-tags.admin.php

at line 108:
replace this:
remove_meta_box(‘tagsdiv’, ‘post’, ‘side’);
with this:
remove_meta_box(‘tagsdiv-post_tag’, ‘post’, ‘side’);

Well, just to add to this… The plugin that caused my issue was “Position Yourself“. After deactivating, everything was back to normal again.

Maybe we can all just build a big database of these outdated plugins and figure out what they all have in common?

I have the same problem.

My wordpress version is 2.8.5 and I tried with disabled plugins+default 2.8.5 theme.

This is a serious Bug, and it seems lot’s of people having trouble with this.

same problem here.

I deactivated wp ajax event calendar and its ok now.

best thing to do.. go through your plugins one by one. more than likely it is a plugin to do with ajax or java of somesort

I have fixed it. It’s ok for now. https://anhblog.net

Exact same problem here. I deactivated the beta version of the plugin, and the tagging immediately starting working again.

I had the same problem on my site truenewzealand.com. It was the “Position Yourself” plug-in for me too. Deactivate and try again.

For me, I just disabled the plugin Wordtube and I was good to go.
