Redmine

Good afternoon, I'm installing redmine on a computer here in the company. I have the following problem, returning the database redmine it was working before, so the Wiki is:

<p><strong style="color: rgb(0, 0, 0); font-size: 9px;">|►</strong><span style="color: rgb(0, 0, 0); font-size: 9px;"><strong> {{lastupdated_at}} por {{lastupdated_by}}</strong></span></p>

<h1 style="text-align: center;">Wiki Infraestrutura TDWorld</h1>

<p> </p>

<h1>Servers</h1>

<h1>Inventory</h1>

Can anyone tell me why is so and can help me?
