    Hola! I really like your plugin! Thank you for let
   us use it. I´m having a database issue I hope you can help me with. I had to 
   migrate site and create new data base. Had some issues with some plugins and 
   in those many “tries and errors” I deleted wp_nextend2_smartslider3 tables and
   re-uploaded backup. After that backuped slider shows ok. I can duplicate and 
   modify, but I can´t erase slides. I can create a new slider but not same luck
   adding slides. “Missing parameter: Slider” messaje shows up. Thank you.

 * Hi [@dongabito](https://wordpress.org/support/users/dongabito/)
 * This “Missing parameter: Slider” error usually happens because of a database 
   error. For instance, when some of our tables are missing. The problem can also
   be that (maybe due to a permission problem with the database user) no new data
   can be inserted to the slider’s tables.
 * First I suggest trying to repair the database at the Plugin list > Smart Slider
   3 > Repair: [https://imgur.com/CF79ihX](https://imgur.com/CF79ihX)
 * If the repair doesn’t help, then I suggest reaching out to your host and asking
   them to look into the database issue.
 * Another solution could be that if you can export your sliders: [https://smartslider3.helpscoutdocs.com/article/408-slider-options#export](https://smartslider3.helpscoutdocs.com/article/408-slider-options#export)
   
   you could do that, then remove the slider’s tables and Repair the database again.
   This should fix the problem they had. Then import the sliders back: [https://smartslider3.helpscoutdocs.com/article/370-import-slider#import](https://smartslider3.helpscoutdocs.com/article/370-import-slider#import)

 * Solved it! Don’t know how after 5th try it worked.
    After that I saw your detailed
   reply. Fact is that I’m not really a database manager expert. Thank you very 
   much, great plugin and support!!
