Steps to reproduce the issue

1. Open installation/language/en-US/joomla.ini
2. Line 249: JPREVIOUS="Site" — this should be "Previous", not "Site"
3. Line 311: JLIB_JS_AJAX_ERROR_TIMEOUT contains "occured" — should be "occurred"

Expected result

• JPREVIOUS should have the value "Previous" (consistent with language/en-GB/joomla.ini, administrator/language/en-GB/joomla.ini, and api/language/en-GB/joomla.ini which all define JPREVIOUS="Previous")
• "occured" should be spelled "occurred"

Actual result

• JPREVIOUS="Site" — appears to be a copy-paste error from JSITE on line 251
• "A timeout has occured while fetching the JSON data." — misspelling of "occurred"

System information (as much as possible)

Branch: 5.4-dev
