it's trying to find a havequest in Parser.lua but in that file it's haveq not havequest so just open up your QuestDBData.lua (not questDB it has to be yourDBdata) change lines 4264 and 4265 from havequest -> haveq. You can open the Lua file and do Control + F to find the line havequest and change it to haveq. This will fix this lua error.
