404 error when I try to save Event Manger Options (settings)

just to narrow down the problem and help us debug the issue is it possible to try the following temporarily:

– deactivating all other plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the default theme to rule out any theme-specific problems

hello!
thanks for the reply!

I’ve tried all this and still not working. keeps giving me the same error.

any ideas?

Which browser are you using? If you try a different browser does that work?

i’m using Firefox.

now i try in Chrome and Safari, with the same error

Which version of Events Manager and WordPress are you using?

WordPres 3.9.2
Events Manager 5.5.3.1

Can you post a link to an image of the error page? That might give us a clue as to what’s going wrong. Thanks.

Thanks. Do you have any strange rules in your .htaccess file? Because you’re being to take to a page on the front-end of your site which isn’t right at all.

no
i have the “standard” htacces
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Do you have any custom code running that relates to the admin area, or any plugins that do?

hello
no. nothing.
i do this:
– deactivating all other plugins to see if this resolves the problem.
– switching to the default theme to rule out any theme-specific problems

and no. nothing solve the problem

one question.
I think it is possible that the plugin does not work because the server / hosting.

I installed WordPress on another hosting and it worked well!

What could it be?
might be something of MySQL? any ideas?

look at me the error that the database:

It could be related to your hosting setup. Do your other permalinks work ok?

Yes!
the rest works perfectly.

how could I send you a summary of the configuration of my hosting? so maybe you could see if there are any parameters that may adjust and make it work.

maybe you can post is on other image sharing site and then post the url here.
