I get a fatal error when attempting to edit entries on any of our MSM sites. It happens through Modify or delete > Entry and through Content > Edit in the CP. Oddly, I can edit any most recent entry in any of our MSM sites by selecting Modify or delete > Most Recent Entry. Here is the error message:
Fatal error: Call to undefined function ascii_to_entities() in /www/eh(redacted)/public_html/system/expressionengine/controllers/cp/content_edit.php on line 243
I updated the installation twice with the same result. The first time I updated EE and my plugins at the same time. Then I rolled it back and tried a second time, and updated each plugin individually, testing it to determine if any of them might have caused the problem before updating ExpressionEngine.
Plugin list:
Low Reorder
Static Page Caching
Wygwam
Playa
Matrix
WB Markitup
CE Image
EE2 ED Image Resizer
