hello
I have the same trouble here. My reach limit is 49 items (including sub items)
When I try to add new item anywhere in my menu, the lasts items just disappear. Sometimes I have the same error message as mentionned (i think), but usually I don’t have message. Only “Menu has been updated”.
Then My only way to make it up, is to disable q-translate, build my menu by using [:en] tag translation, then activate qtranslate again.
Very annoying, especially because website become unreadable when all languages are displayed at the same time during disabled qtranslate-X.
What can we do ? Iwant to hack the admin files, but where should I go ?
(and I don’t see why it should have anything to do with php limitation since it works very well when qtranslate if off…)
