Imagick php error

After updating the add-on "ds - Event Calendar", I've begun to get a php error when I'm saving content I've edited:

PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20100525/' - cannot open shared object file: No such file or directory

I deleted the calendar block and uninstalled the calendar add-on, but I'm still getting this error. The error is not consistent. It happens on Save, but only sometimes. I can work around it (by using browser's Back button) without losing my work, but it's troubling to the less-technical people who work on the site.

I'm on, using a version of the Elemental theme that I made. The site can be found at I've read the bullet points in the release notes about imagick (, but I *think* I built this site in back in October. Release notes don't have release dates on them, and I may have updated once, not sure.

Can someone point me in the right direction?

Hi kcbenson,

I see the error on the front end. After a refresh it does go away.

Do you remember the date that you updated the add-on?

Have you checked the concrete5 logs to find the date of the first occurrence of the error?
Dashboard > Reports > Logs

Does the first occurrence happen after updating the add-on?

An option is to make a full backup to install locally. You can then enable debug error output to potentially see where the error is coming from.
Dashboard > System & Settings > Environment > Debug Settings > Error Detail > Show the debug error output
