Issue after using a list plugin

Hello,

I was trying several listing plugins for my site
Since no one was working as I wanted, I deleted them from my site.

Since then, I have a strange behavior with some widgets:
– Links
– Categories
– Latest posts

For example, if I use the LINK widget, it will only show me blank spaces.
Categories will show nothing
Latest Posts will show all my ages titles, not the latest posts…

I first checked that the plugins were correctly uninstalled (wich is the case). I then tried to reinstall wordpress. No joy.

I then went into my SQL admin page and saw that there was 2 new tables.
After checking that it wans not something that wordpress needed, I dropped these 2 tables.
It did not change anything…

I do’t know what else to do as everything else is working fine (categories are correct, posts are showing as they should, …)

Are they some files that the automatic wordpress installation does not replace ?
Could it be an issue into a SQL table ? (like the IDs) ?

I’m really clueless and any help would be appreciated

If you need more informations, feel free to ask !

Thank you !
