Minor website fix

I own 2 websites which list properties for sale and for some reason it is not allowing me to delete listings or add new ones. I need this corrected asap. I own 2 websites with this same issue that need to be resolved so your bid is for fixing both websites and then at least 30 day followup to ensure they continue to work. I am sure this is a simple fix for those who really know what they are doing. I assume it will take less than an hour or so to complete on both sites. I will give the URL to the winning bidder as if you are familiar with these type of sites you probably already have an idea of what the problem is. Thank you for reviewing my project!
