You can sue under 42 U.S.C for violations of your constitutional rights, including false arrest and imprisonment. However, judges have absolute immunity for their actions within the scope of their employment. So, it depends on who made the mistake. Law enforcement officers have a more limited, "qualified" immunity.
If you violated the Protection Order before it was dismissed you would not have a valid claim. However, based on the way you asked the question, I assume the violation itself (not the arrest) occurred after it was dismissed. If that is so then because there was no legal basis for your arrest, you would have the right to sue for violation of your rights. However, whether the suit is successful depends largely on the reason why you were arrested. If the "victim" made a complaint knowing the PFA had been dismissed you could sue her for malicious prosecution. If it is due to a "clerical" error then you may have a hard time winning the case because government officials have "immunity" under Alabama law. They cannot be sued for mistakes they make while acting within the scope of their employment. You would only be successful if you could prove it was done maliciously, etc. which is hard to do.
