after trying to add the tab again with the same content i find that it just pdate the meta value in postmeta table and nothing changed except one thing:
this is an example:
a:1:{i:0;a:3:{s:5:”title”;s:27:”tab title”;s:2:”id”;s:25:”documents-telechargeables”;s:7:”content”;s:82:”test”;}}
new one
a:1:{i:0;a:3:{s:5:”title”;s:27:”tab title”;s:2:”id”;s:25:”documents-telechargeables”;s:7:”content”;s:142:”test”;}}
s:142 and s:82
what is this? and does it have relation with the problem??
i lost a big work in tabs
i hope that you fix this problem
