Really need permalink help

I am having a big problem with my permalink. I posted about it in question # 2 on https://www.gluedideas.com/support/viewtopic.php?id=116

But basically some of my pages seem to not have there permalink style changing back to “default” from “nice” style even though i changed it in my admin. Furthermore, since it is trying to read an old permalink, i have since moved the location of the page and it results in a page not found.

i exported my wp file and i noticed in the xml this line for one onf the not-working pages:

<guid isPermaLink=”false”>https://fenderbluesjunioramps.com/speakers/</guid&gt;

but the working pages have this:

<guid isPermaLink=”false”>https://fenderbluesjunioramps.com/?page_id=6</guid&gt;

i don’t know why some of the pages not stuck with old permalink steructure. is there any way to clear it from somewhere so i can fix this issue? thankS!!!!
