maybe you have an error function dude. what is your activity before you get this error? editing your function file? or installing new plugins or themes?

maybe you can rename your themes folder (your new themes). just like >> currectthemes, and rename it to curretthemes2 or somethink else

for chek your core problem, you can switch your themes with wp default themes, like twenty ten.
if you still have an error, i think this is not your themes problem.
next, you can inactive all your plugins. see, just like before, if you still have an error, this is not your plugins problam.
or you can change both of my sollution in one time.

my last sollution. if you already change to default themes and inactiving all of plugins. then you should reinstall your wordpress.

Please do not suggest that people edit core files.

sorry for that. and i wont editing any core files.

but I have same problam like this for a weeks ago. and I do what your sollution. every one of your sollution. but its make me sad. because my sites wont back to normal. it because de version in core files wont update when I update my sites.

but I hope @mhkpl2017 will success with your sollution. Sorry but I just want to help

maybe you should explaining your case again? i dont undersand what your problam. and maybe you can explaining with an image.

I thinnk you should doing like this.
1. go to your database pages, in my case I use phpmyadmin. then open your sites database.
2. find option table. in my case, my prefix is sa. so my option table looks like sa_options.
3. after that, find your database version. it placed in db_version collumns. if you already know your database version. go to the next step.
4. go to your root directory of your website.
5. open version.php inside wp-includes folder. replace $wp_db_version value with your database version. then save.
finish

in other alternative. you just close your php code first. like @bcworkz first answer. in all you need. just replace your code like this

<?php  if(is_single()){ ?>
<meta property="og:title" content="<?php the_title_attribute(); ?>" />
<meta property="og:type" content="article" />
<meta property="og:url" content="<?php echo the_permalink(); ?>" />
<meta property="og:image" content="<?php echo $img_src; ?>" />
<?php };?>
