For a long time now (and as previously reported) under certain conditions (e.g.at PPRuNe Forums > Aircrew Forums > Bizjet, Ag Flying Ga Etc [[url]https://www.pprune.org/biz-jets-ag-flying-ga-etc-36/] clicking on the 'Aircrew Forums' link [[url]https://www.pprune.org/aircrew-forums-135/] I get see an error thrown by
vbseo "
Error: Cannot unset string offsets in ..../vbseo/includes/functions_vbseo_vb.php on line 1262".
Also just going to https://www.pprune.org/aircrew-forums-135 I get the same error.
Since
vbseo seems to be a non-longer supported plugin for vBulletin I was wondering if in fact PPrune is developed on top of VBulletin?
