Title: Logfile pattern analyzer: Fix crash for first rule without regex pattern Class: fix Compatible: compat Component: multisite Date: 1713341414 Edition: cre Level: 1 Version: 2.2.0p26 The "Logfile pattern analyzer" page crashed when the first "Logfile pattern" rule in place did not hold a regex pattern and a later rule did hold a regex pattern. The rendering of the table of rules would crash with C+: Internal error: list index out of range C-: This is fixed and all rules are rendered as expected.
