I dont know how you can fix it, but it was caused cuz you used "quotes", and the new server doesnt like "quotes" at times. Sometimes it seems like
it does, sometimes it seems like it doesnt.
I just checked my own story and it seems ok. I write it using Wordpad and C&P it once it is done. The only special characters I use are speech quotes
( " ) and descriptive quotes ( ' ) and I haven't had any problems with those.
I have to admit that I check my writing better now than before since we only have a limited time before the edit button disappears
