SPRINGFIELD, Ill. (AP) — A portal through which tenants impacted by COVID-19 can apply for rental assistance is back online after a programming problem compromised some personal information.

An applicant’s Feb. 1 call to the Illinois Housing Development Authority’s call center alerted the department to the problem.

Agency spokeswoman Amy Lee tells The (Bloomington) Pantagraph the applicant said they saw someone else’s document when they logged into their rental application.

The portal went offline and all access to external users was blocked while the agency resolved the issue. The portal was offline until Feb. 3. The agency found the exposure was the result of a coding error.
