Undefined Variables with new VaultWiki installation

As reported by Xenforo Admin CP

Just in the past day I have installed VaultWiki Premium on a currently in-development closed Xenforo forum (I plan to import a data from another active forum at a later stage). Since installing VaultWiki I have noticed growing entries in the server error log in the Xenforo Admin CP.

These are the errors I'm getting, as a result of changing various settings in the admin area:

Code:

ErrorException: Undefined variable: bbcode - vault/core/controller/dm/prefix/vw.php:285[/B]

array(3) {
  ["url"] => string(77) "https://path/to/admin.php?wiki/&panel=prefix&do=save"
  ["_GET"] => array(3) {
    ["wiki/"] => string(0) ""
    ["panel"] => string(6) "prefix"
    ["do"] => string(4) "save"
  }
  ["_POST"] => array(8) {
    ["panel"] => string(6) "prefix"
    ["do"] => string(4) "save"
    ["_xfToken"] => string(8) "********"
    ["generic"] => string(4) "wiki"
    ["title"] => string(8) "Template"
    ["bbcodetag"] => string(0) ""
    ["sbutton"] => string(4) "Save"
    ["url"] => string(69) "https://path/to/admin.php?wiki/&panel=prefix"
  }
}

Code:

ErrorException: Undefined variable: filename - library/vw/XenForo/Option/Seo.php:26[/B]

array(3) {
  ["url"] => string(82) "https://path/to/admin.php?options/save/vw_server_settings"
  ["_GET"] => array(1) {
    ["options/save/vw_server_settings"] => string(0) ""
  }
  ["_POST"] => array(3) {
    ["options"] => array(12) {
      ["vw_enabled"] => string(1) "1"
      ["vw_bburl"] => string(41) "https://path/to/"
      ["vw_cdn_url"] => string(0) ""
      ["vw_filename"] => string(4) "wiki"
      ["vw_protocol"] => string(1) "2"
      ["vw_titlevar"] => string(5) "title"
      ["vw_spaces"] => string(1) "0"
      ["vw_seo"] => string(1) "1"
      ["vw_languageid"] => string(1) "1"
      ["vw_wiki_name"] => string(4) "Wiki"
      ["vw_apikey"] => string(16) "[removed from support post]"
      ["vw_cache_life"] => string(1) "7"
    }
    ["options_listed"] => array(12) {
      [0] => string(10) "vw_enabled"
      [1] => string(8) "vw_bburl"
      [2] => string(10) "vw_cdn_url"
      [3] => string(11) "vw_filename"
      [4] => string(11) "vw_protocol"
      [5] => string(11) "vw_titlevar"
      [6] => string(9) "vw_spaces"
      [7] => string(6) "vw_seo"
      [8] => string(13) "vw_languageid"
      [9] => string(12) "vw_wiki_name"
      [10] => string(9) "vw_apikey"
      [11] => string(13) "vw_cache_life"
    }
    ["_xfToken"] => string(8) "********"
  }
}

I was also seeing two other errors caused when editing wiki pages, one fatal, but they seem to be solved after applying the code edit offered in issue 4888. Nevertheless I've included the error messages for reference.

Code:

ErrorException: Fatal Error: Call to a member function free() on null - vault/core/controller/db/xf.php:367

Appears to be fixed using code edit from issue 4888

Code:

ErrorException: Undefined variable: subscriptions - vault/core/model/cron/deferred/instantsubalert/vw.php:212

Appears to be fixed using code edit from issue 4888

Thanks. These first two errors are now fixed in the next release. The first only occurred when creating a new wiki-prefix with certain values, and the second occurred whenever a specific one of the add-on's options was changed - this allowed the admin to sometimes select an options combination that was invalid. Your selected combination looks fine to me, though, so you shouldn't have to worry about that.
