Couldn't edit my website, while clicking edit button in my website, getting this error. I tried removing my custom built module too. Still getting the same error. Can anybody figure out what this error for and how should it be resolved? It happened after making some changes in the template I have created. I have undone my changes once I faced the error. Still, it shows the error. Is there any wrong in my template?
Here is my template

<template id="head" name="Header">
    <section class="headers">
        <div>  
        <ul class="menu-head"> 
            <li class="menu-list-head"> 
                <a href="home">Home</a> 
            </li> 
            <li class="menu-list-head"> 
                <a href="games" class="menu-head-parent">Games</a>
                <ul class="hide" style="float: none; width: 12em;"> 
                    <li class="hide-menu-list"> 
                        <a href="indoor">Indoor</a> 
                    </li> 
                    <li class="hide-menu-list">
