I filed back in May. On the IRS site, the status was shown with colored bars initially, but now those bars are gone and it just says "still processing."

After the tax return has been Accepted by the IRS (meaning only that they received the return) it will be in the Processing mode until the tax refund has been Approved and then an Issue Date will be available on the IRS website.
See this IRS website for federal tax refund FAQ's - https://www.irs.gov/refunds/tax-season-refund-frequently-asked-questions

Call the IRS: 1-800-829-1040 hours 7 AM - 7 PM local time Monday-Friday
When calling the IRS do NOT choose the first option re: "Refund", or it will send you to an automated phone line.
So after first choosing your language, then do NOT choose Option 1 (refund info). Choose option 2 for "personal income tax" instead.
Then press 1 for "form, tax history, or payment".
Then press 3 "for all other questions."
Then press 2 "for all other questions."
- When it asks you to enter your SSN or EIN to access your account information, don't enter anything.
- After it asks twice, you will get another menu.

Press 2 for personal or individual tax questions.
Then press 4 for all other inquiries
It should then transfer you to an agent.

The IRS states:

WHERE’S MY REFUND STATUS BARS DISAPPEARED

"We have gotten many comments and messages regarding the IRS Where’s My Refund Tool having your orange status bar disappearing. This has to do with the irs.gov where’s my refund site having too much traffic and lagging. This is causing images not to display and information about your federal tax return to not show up. This has happened every year since the tool was first available. This has nothing to do with you being flagged or your return being denied. Status Bars Disappeared for many Americans who filed early. This also can have to do with your browser settings as well as your cache. Please try using a different browser such as Chrome or Firefox. Also, clear your cache in your browser settings."

When checking on the status of your refund at the IRS Where's My Refund (WMR) site, you may get the message: We cannot provide any information about your refund. You must wait at least 24 hours after you get the acknowledgment e-mail that your tax return was received by the IRS.

You might receive this message because:

• Your e-filed return was accepted (received) by the IRS less than 24 hours ago. Wait at least 24 hours after acceptance before using WMR.
• Your return is still pending.
• You never e-filed. You can quickly find out if you did by checking your status.
• If you don't see a status, go through the TurboTax File section again. Be sure to go all the way to the end and select Transmit my returns now.
• You mailed your return less than 4 weeks ago. Paper-filers should wait four weeks before using WMR.
