Title: Parse errors and blank screen after upgrade Last modified: August 30, 2016 --- # Parse errors and blank screen after upgrade * [llsn](https://wordpress.org/support/users/llsn/) * (@llsn) * [10 years, 11 months ago](https://wordpress.org/support/topic/parse-errors-and-blank-screen-after-upgrade/) * I am getting these cryptic errors after upgrading my blog. I tried upgrading because the blog content stopped showing, although it show the title and header of the blog. I tried changing the theme to the default theme, and that showed the content, but it did not show the archives, or give me log-in, etc… * In trying to troubleshoot that, I decided that I would try to upgrade the WP install because I thought that some of the important files would be updates and that was what was causing the missing content. (However, I have never been able to automatically install the updates, so I probably installed it incorrectly from the beginning.) I tried the manual install – from [here](https://codex.wordpress.org/Updating_WordPress) and [here](https://codex.wordpress.org/Upgrading_WordPress_Extended). * It did not work. * This is the message I get when I try to view my blog: `Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in/ homepages/9/d184491553/htdocs/blog/wp-includes/locale.php on line 21` I see nothing else. * This is the message I get when I try to upgrade my blog admin and attempt to login to the site: * ``` Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /homepages/9/d184491553/htdocs/blog/wp-admin/plugins.php on line 374 ``` * I see nothing else. * The blog is installed in a subfolder on my domain – i.e., somedomain.com/blog/ * I was upgrading from a version several years old, due to not having been able to upgrade automatically for a long time, so I’m not sure what version I’m using. And, if it helps: Yes I made backups of my files, but I did not find a .htaccess file, though. And, yes, I did deactivate my plugins before upgrading – there were only 2.

Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old copies of files & folder on your server before uploading the new ones. Read the [Manual Update ](http://codex.wordpress.org/Updating_WordPress#Manual_Update) directions first. – **If you haven’t already done, always backup everything ( including your database) before doing any actions, just in case something really goes wrong.** * Thread Starter [llsn](https://wordpress.org/support/users/llsn/) * (@llsn) * [10 years, 11 months ago](https://wordpress.org/support/topic/parse-errors-and-blank-screen-after-upgrade/#post-6340839) * Thanks for the response. Manual updating is exactly what I did, following the manual update instructions as I linked in my question, and also because automatic updating doesn’t and hasn’t ever worked for me. * If you have any other help, I’d appreciate it. * Moderator [t-p](https://wordpress.org/support/users/t-p/) * (@t-p) * [10 years, 11 months ago](https://wordpress.org/support/topic/parse-errors-and-blank-screen-after-upgrade/#post-6340857) * Have you tried: – Flushing any caching plugins you might be running, as well as server and/or browser caches. – deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin( s). – If you can’t get into your admin dashboard, try [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F) by [FTP](http://codex.wordpress.org/FTP_Clients). If that resolves the issue, reactivate each one individually until you find the cause. Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder (if you have created such folder). The easiest way is to rename that folder to mu-plugins-old. – switching to the unedited default Twenty Fifteen theme for a moment using the WP dashboard to rule out any theme- specific issue (theme functions can interfere like plugins). If you don’t have access to your admin area, use [FTP ](http://codex.wordpress.org/FTP_Clients), or your web-host’s cPanel or whatever file management application your host provides. Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme. That will force your site to use it. – If all the above steps do not resolve the issue, then try **MANUAL** re-uploading WP. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config. php file and the /wp-content/ directory. You may need to delete the old copies of files & folder on your server before uploading the new ones.

Unfortunately, none of these solutions work. * I’m just going to create a new WP blog and possibly try to get the content from the old one some other way. * Moderator [t-p](https://wordpress.org/support/users/t-p/) * (@t-p) * [10 years, 11 months ago](https://wordpress.org/support/topic/parse-errors-and-blank-screen-after-upgrade/#post-6340863) * – Blank white page is a PHP error. This problem can be caused by a variety of issues, including: (1) Bad theme (2) Bad plugin (3) Bad install/upgrade (4) you exhausted the memory limit (5) It could also mean that there is an issue with your web hosting server. 1 and 2 are more common. * – Since the problem can be caused by any number of things, check the error logs on your server for a more specific error message. If you need help locating them, ask your hosting provider to help you with that. – Review this useful Codex: [http://codex.wordpress.org/Common_WordPress_Errors#The_White_Screen_of_Death](http://codex.wordpress.org/Common_WordPress_Errors#The_White_Screen_of_Death) Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘Parse errors and blank screen after upgrade’ is closed to new replies. ## Tags * [parse-error](https://wordpress.org/support/topic-tag/parse-error/) * [troubleshooting](https://wordpress.org/support/topic-tag/troubleshooting/) * [upgrading](https://wordpress.org/support/topic-tag/upgrading/) * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 5 replies * 2 participants * Last reply from: [t-p](https://wordpress.org/support/users/t-p/) * Last activity: [10 years, 11 months ago](https://wordpress.org/support/topic/parse-errors-and-blank-screen-after-upgrade/#post-6340863) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
