WordPress is a wonderful platform, even though initially was for blogs, now it is a fully featured platform to build functional websites. WordPress comes with the unique advantages of an open-source platform, fully customizable at zero cost by making the task of web development easier even for those who don’t know to code.
WordPress is built on PHP language for scripting and MySQL database management at the backend. However, the catch is that you don’t need to know both of these to use WordPress. In fact, a basic understanding of these two technologies can surely help you to do it in a better way and troubleshoot problems easily by understanding how things work.
Common WordPress issues
Even though it has many advantages, just like any other technology, it too has some imperfections, and once in a while, you may find some errors while rendering WordPress applications. There is a big and constantly engaged community of WordPress developers and experts, where you may get the solutions for almost all WordPress related issues. You may read to know a few of the major problems and available solutions.
#1. WordPress is showing an error message stating “Cannot modify header information – headers already sent.”
This message is shown when there are some problems with the stray characters you use. They may not be visible like space at the starting of an opening tag or towards the closing tag. You have to check the end part of the error message to identify which filename creates the warning and work on it.
There are two fixes for this issue:
- If you haven’t edited things recently, then it is ideal to replace that file causes errors from your last backup.
- If there is no copy of working backup, you may download the specific file and open it using any of the text editors which won’t hide characters, i.e., Windows Notepad or so.
It is ideal not to use the common word processing applications like MS Word as these may insert some hidden characters in the doc. Always make sure that the file naming starts with ‘<?’ and there is ‘?>.’ at the end. Double check for any hidden characters as spaces by placing after the tag and delete if any extra space.
#2. Database file backups for WordPress are very large
As we know, it is crucial to ensure frequent backup of the WordPress database. To ensure additional security, it is advisable to keep two, three, or even four copies of the database file kept at different locations in case of you find the primary backup file is corrupted at any point. However, doing this may be a problem if there are huge backup files.
In many cases, database backup files tend to occupy a significant space due to the reason that the plug-ins used to store a huge amount of data. Say for example, if you use plug-ins for data statistics or to block spam, these tend to generate a huge volume of data in shorter periods. All these data get stored within the backup files.
As a solution to this, the leading backup tools for WordPress database allow to custom choose only the specific tables to be included in the backup file. Select any tables which have vital information about the daily working of your site and skip those tables which only generate data which is not crucial for the functioning of your website. Image files also tend to use large storage space. So, if you have images which are no longer needed, then you may delete those files and free up some space.
#3. The changes are not saved
Many complain about the changes in WordPress not getting saved. This is an easy problem to fix. You may have to force a page to reload from the server by using some web browser reload commands to accomplish it. Web browsers also may have copies of data stored in the cache of the computer. This is to enable faster loading on subsequent visits to the website. Once you reload the page, you get this stored copy from the cache, which may not reflect the latest changes made.
So, in order to force the browser to reload the most updated page directly from the server, you can use the below commands.
- Hold down the Ctrl/CMD + Shift buttons and press “R.”
- On browsers like IE, simply hold down the shift key and then click the Refresh button.
Be aware that the shortcuts may not work properly on based on some browser settings. The proxy sites won’t be having caches so load only the latest version from the server.
Sometimes, even after doing this, you may still face the problem of the WordPress site not getting saved. Then the problem may primarily be user-generated than browser-generated. In some cases, a WordPress plug-in downloaded may change the working pattern of the browser cache. If you think a plugin causes the problem, then you have to check the documentation about it and find out the effect of the plugin in the browser cache.
Some common problems in which it may look like your WordPress is not loading or saving the changes may include some inherent mistakes of the site code or due to the WordPress version. You have to recheck the code and identify any possible errors to be corrected to work on this issue.
#4. Getting error messages while deleting old pages or posts
This is a very common problem due to many causes, which are difficult to narrow down. It is more of a sporadic problem and also difficult to track. If you face this problem, then it may be due to the reason that you have installed a specific plug-in which further interferes with the delete or edit functions of your website. In fact, there is no off-hand list of those plugins which do this, so if the problem persists, you may have to try deactivating all the plugins and then reactivate them one by one to see what causes the issue.
