Would someone give me some advice please. I have the same issue – I upgraded the tag cloud plugin and got the error message. But I do not know what I am doing wrong because I cannot even go back to my dashboard to delete, un-install or undo the plugin upgrade. * Each time I try to go to my dashboard or even view my website, it just directs me back to the error message: Fatal error: Class ‘Rickard\UTCW\Widget’ not found in /home/zarachiron/zarachiron.com/wp-includes/widgets.php on line 324 * Please help. * [valentina.desantis](https://wordpress.org/support/users/valentinadesantis/) * (@valentinadesantis) * [13 years ago](https://wordpress.org/support/topic/fatal-error-after-upgrading-1/#post-3724208) * Hello * I’ve got the same problem but my question is: at the moment I can’t access my pc where I use filezilla – now I’m at work and I can’t download filezilla… Can I use something else different filezilla to remove the last version of this plugin?

You can do this either with something like Filezilla, but you can also use Windows Explorer. * Just type, in the Windows Explorer address bar (not Internet Explorer, though you can use that too): * ftp://nameofyourwebsite.com * When prompted, fill in your login details, navigate to wp-content/plugins and rename/delete ultimate-tag folder * Your website will now work and you can log in to your admin panel again * [typopath](https://wordpress.org/support/users/typopath/) * (@typopath) * [13 years ago](https://wordpress.org/support/topic/fatal-error-after-upgrading-1/#post-3724220) * yap, same thing happened here. going back. * Plugin Author [Rickard Andersson](https://wordpress.org/support/users/exz/) * (@exz) * [13 years ago](https://wordpress.org/support/topic/fatal-error-after-upgrading-1/#post-3724240) * Sorry about this issue, was trying to modernize the plugin and accidentally removed php 5.2 compatibility. Trying to get 5.2 compatibility back broke it for the rest of users. * I’ve just updated to 2.2.2 which should resolve this issue. * [liquidguru](https://wordpress.org/support/users/liquidguru/) * (@liquidguru) * [13 years ago](https://wordpress.org/support/topic/fatal-error-after-upgrading-1/#post-3724247) * Thanks.
