Repeated warning: "simplexml_load_file(): I/O warning : failed to load external entity ".../xml/Menu/Activity.xml"
Environment: Observed in Civi 5.10 and 5.7 with bknix-min (PHP 5.6 / MySQL 5.5). Haven't tested other environments yet.
Steps to Reproduce: Login as admin. Use
/civicrm/clearcache (i.e. the browser-based clear)
- The warning message references many Menu XML files, but I think the first is the only the matters. It actually has an XML entity (
&); removing that entity prevents the warnings (but would obviously break that menu item).
- It seems strange that
&would be regarded as an external entity.
