If you're having trouble logging onto your Wachovia online banking account today, you're not alone.

Wachovia said this afternoon that a "systems issue" was intermittently disrupting service for its online customers. It also was affecting customers trying to access Wells Fargo Advisors Online, a brokerage service formerly known as Wachovia Securities.

"We are working to correct the situation as quickly as possible," Wachovia said in a statement. "We appreciate customers' patience and sincerely apologize for any inconvenience this may cause."

Despite the problem, many customers are able to access their accounts online, said spokesman Josh Dunn.

The problem also doesn't affect Wachovia's ability to serve customers at its branches or ATMs, or customers who want to access their account by phone.

Wachovia also is reassuring customers that the data in their accounts remains "safe and secure."

Adding to the confusion among customers is that this weekend Wachovia credit cards are being converted to Wells Fargo credit cards, a move that the bank previously said would prevent customers from accessing their credit card account online beginning today through Sunday. But Wachovia spokesman Josh Dunn said that the broader disruption that is preventing customers from accessing other accounts online, such as savings and checking accounts, is unrelated to the conversion.

Despite the conversion, Wachovia customers can continue to use their credit cards this weekend.

San Francisco-based Wells Fargo acquired Charlotte-based Wachovia in 2008.
