Minor Wordpress Edits

Hi. I had previously hired a freelancer to add an infinite scrolling feature on my Wordpress Blog plus a few other minor layout edits. However the implemented scrolling solution created a few unwanted problems with the blog so I need to fix this. The main issue: if I add an image gallery to a blog post via shortcode, the gallery images are not shown on the main blog feed. Instead, the shortcode is visibly displayed in text. For example: [gallery link="file" type="square" ids="3001,3002,3003"]. I need the gallery of images displayed and not this text. Also, when viewing and scrolling the blog on mobile devices, the blog’s side bar briefly appears after every 5 entries or so. I need the side bar added to the end of the blog feed only without it appearing and disappearing. Results from searches, Tags, Categories and Author posts will need the edit applied as well as the main Blog feed. * The site’s Blog can be found here: [login to view URL] * You’ll be provided with a test site and log in details once the job as been awarded. * I will then copy these edits to my main website, so please let me know which files have been edited to allow for this. * You will be given access to the test site and FTP access to the theme file directory. * You will be completing minor edits to an existing site. Please don't waste your time by bidding way off budget * Let me know if you need more info and I'll be happy to help.
