I'm missing all the usual processing tools in the Vector menu in QGIS 2.16 (e.g. Vector Overlay, Analysis, etc). They do appear in the processing toolbox but there's no sign of them in the Vector menu. Has anyone come across this issue?
Just enable the processing plugin and the menu will be back. Note that you can go to Processing => Options => Menus, to configure in detail which algorithms will be available in the menu.
I had this problem in QGIS 3.8. I just went into manage and install plugins searched for processing, which is a core plugin. I unclicked this to disable the plugin and then reclicked to enable. This fixed the problem and vector reappeared on the toolbar.
I had the same problem of having two vector-menus (my QGIS 2.18 (Ubuntu 16.04) set to Finnish): one that was actually in the language set for QGIS (Finnish) and other that was in English. The two menus together had all the vector functions that QGIS normally would have. This problem didn't occur when using QGIS set to English.
In my case, to lose the second vector-menu while using the QGIS set to Finnish, I had to: Processing Options > Choose "Reset to defaults" besides "Menus (requires restart)" and it worked (after restarting QGIS, of course).
I had the same problem to find the "points in polygons" entry in the Vector's menu, however with a little trick, I found a work-a-round, which immediately solved my problem. Here is the solution (sorry for the German menu, but you'll find the corresponding items):Menu: Ansicht>Bedienfelder>Werkzeugkiste (STRG+ALT+T)This brought a toolbar on the right side up--> then type points in polygons and select the item showing up, which brings a pop-up window for using the feature.
Retro restaurant menu in the vector file. Besides the fact that it looks really cool, has the right colors and fonts hand-picked just right for your prints and website templates, theres nothing else to say but Download and enjoy!.
